I was curious while you are in Belize what do you do? Reservations or Just Show Up?
I will be in Caye Caulker in about 4 weeks for about 4 or 5 days and I wanted to do the Raggamuffin tour to Hoi Man Choi and was curious if you thought I should make reservations or just show up? I dont like making reservations because I want to just play everything by ear as I go but I also dont want to get there and be told no because they're full. I'm traveling solo so maybe that will help.
In my experience you will rarely(if ever) have the problem of a tour/activity being 'full'...they nearly always manage to squeeze another person on (or if there are far too many people,put you on another boat/bus etc.which is following the same schedule.
Its more likely that a trip is cancelled because there aren't enough people...or that you have to wait a couple of days for a trip to start...no problem if you are not on a very tight schedule...
You're going at a busy time of year, but generally there's no need to make advance tour reservations. For one thing weather can be a factor. Once on the island, you might check with tour operators the day before you want to go.
I would make reservations only if travelling at busy holiday periods such as Christmas & Easter, or if arriving on a weekend and had a specific hotel that I wanted to stay at.
I'd book the Raggamuffin tour at least the day before if not more; the day we went they were turning people away. As lucapal says, that's not a problem if you have wiggle room in your schedule - just go a different day. FYI, it's "Hol Chan" not "Hoi Man Choi" unless we're talking about different places. ;-)
