DockDoc™ | The Free Cruise Arrival Planner That Tells You If Your Plan Is Actually Safe

What Is DockDoc™?

DockDoc is a cruise arrival planner built by Royal Galveston Shuttle. You enter your flight arrival time, which Houston airport you’re flying into, your shuttle type, and your cruise sail date. It spits out a step-by-step transfer timeline and a risk score from 0 to 100 that tells you whether your plan is safe, borderline, or genuinely cutting it close.

There’s nothing else like it for Galveston cruise passengers.

The generic advice you’ll find everywhere — “arrive at the port two to three hours before boarding” — doesn’t account for your actual flight time, the hourly shuttle schedule, how long baggage claim takes, or what traffic on I-45 looks like on a Saturday morning when three ships are loading. DockDoc does.

Here’s What It Looks Like in Practice

The best way to understand it is to see two real examples.

Example 1: Same-day arrival — Risk Score 58/100

Royal Caribbean sailing May 21, 2026. Flight into IAH landing at 8:35am. Checked bags. Shared shuttle. Target terminal arrival 12:30pm.

On paper, that looks fine. Almost four hours from landing to the port. In reality, here’s what DockDoc shows:

• 8:35 AM — Flight lands
• 9:20 AM — Baggage collected (45 min estimated for checked bags)
• 10:00 AM — Next shared shuttle departure
• 12:00 PM — Arrive at Galveston port (2 hour transfer from IAH)
• 12:30 PM — Target check-in
• 30 minutes of buffer

Thirty minutes. That’s it. If your bag takes an extra 20 minutes, if traffic is slow through Texas City, if the shuttle is five minutes late — you’re now at the port after your target time with final boarding closing at 3pm and a line still ahead of you.

DockDoc flags this as medium risk and tells you exactly what to do about it: consider arriving the day before, book an earlier flight, or have a private car on standby in case the shared shuttle timing doesn’t work out. It even gives you a decision point — if your bags aren’t collected by 9:20am, switch to Plan B immediately.

Example 2: Arrive the day before — Risk Score 20/100

Same cruise, same airport, same shuttle type. But the flight arrives the day before at noon.

• 1:00 PM — Shared shuttle to Galveston hotel
• 3:00 PM — Hotel check-in
• Next morning, 25-minute transfer from hotel to terminal
• 695 minutes of cushion built into the plan

Low risk. DockDoc confirms the shared shuttle is the right call and tells you the plan is solid even with normal delays.

Two plans, same cruise, same shuttle. One has 695 minutes of cushion. The other has 30. That’s the kind of thing DockDoc catches before you book.

Why Galveston Timing Is Trickier Than Most Ports

If you’ve cruised from Miami or Fort Lauderdale, Galveston works differently. The port is 70 miles from George Bush Intercontinental Airport. In good traffic that’s 90 minutes. On a busy cruise weekend it can be well over two hours.

Shared shuttles run on the hour. Miss a departure by five minutes and you’re waiting another 60. That one hour can flip a comfortable plan into a stressful one.

And the ship doesn’t wait. All the major lines sailing from Galveston — Royal Caribbean, Carnival, Disney, MSC, Norwegian, Princess — close boarding at least an hour before sail time. Once that gangway goes up, it’s done. You’re not getting on.

This happens more than you’d think. Not because of disasters — because of plans that had no margin for anything to go slightly wrong.

What You Get

A risk score. A number from 0 to 100. Under 30 means you’re in good shape. 30 to 60 means it’s doable but tight. Over 60 means something needs to change.

A minute-by-minute timeline. Exact times for every step — landing, baggage, shuttle pickup, arrival at the port. Not estimates. A schedule.

A shuttle recommendation. Shared or private, based on your actual numbers. If your cushion is tight, DockDoc tells you the shared shuttle is a risk. If you have room, it tells you shared is fine and saves you $165.

A contingency plan. For tighter scenarios, DockDoc tells you exactly when to abandon the shared shuttle and switch to a private car, and when to call your cruise line’s port desk.

Hotel and restaurant picks. If you’re staying overnight in Galveston, it recommends hotels by proximity to your terminal plus dinner and breakfast spots worth knowing.

A downloadable PDF. Everything in one printable document — timeline, shuttle contacts, hotel picks, contingency steps. $4.99.

Shared or Private: How DockDoc Decides

Most people pick their shuttle based on price. DockDoc picks based on timing.

Shared shuttles from IAH run hourly, 8am to 5pm, at $30 per person. They’re the right call when your schedule has enough cushion to absorb a wait or a slow bag.

Private shuttles start at $195 and go directly to your terminal on your schedule. They’re worth it when your flight lands late, when your buffer is thin, or when the idea of waiting an extra hour for the next shuttle departure makes your stomach drop.

For the same-day May 21, 2026 scenario above, DockDoc recommends shared but flags the 30-minute buffer as a real concern and notes that anyone with checked bags and any anxiety about timing should consider private.

Who Should Use It

If you’re flying into Houston the same day your cruise sails, use it. Same-day arrivals are where people get into trouble and where the generic advice fails you most.

If this is your first time cruising from Galveston and you don’t have a feel for the distance or the shuttle schedule, use it.

If you’ve ever typed “what time should I take the shuttle from IAH to make my cruise” into a search box or a cruise forum, use it. DockDoc answers that question for your specific flight, not in general.
