This is the advice I give guests when they ask if they can take the water taxi:
Yes, you can get here by water taxi. We generally suggest that guests take the plane to get here and the water taxi on the way back. Here's why: when you arrive at Belize International (which is in Ladyville), you must go through immigration before you get your bags and then customs. If you take the water taxi, once you find your bags, you must take them outside, hail a cab and have the cab take you to the Municipal Airport in Belize City. There you get your bags, again, and take them to the pier where they are loaded onto the water taxi. The trip lasts about one hour and forty minutes. The water taxi can be very crowded. (see picture below) Once here, you have to get your bags again, and take them to another taxi. The taxi then takes you to your hotel. You can walk to your hotel, but even the best luggage doesn’t roll well on sand streets. The cost of the taxi in Belize City is about $25 . The water taxi fare to the island is $30.00 per person. The taxi in San Pedro can run anywhere from $3 US to $7 US depending on where you are staying. On top of that, you have been traveling all day and you have no control over the weather. A two hour boat ride in 75 degree weather if overcast feels very wet and cold. Depending on your arrival time into Belize International, you may not make the last water taxi, which leaves at 4:30. The last plane out of International for San Pedro leaves at 5:30, and you arrive in San Pedro at 5:55.
