Shoot.... I'm no expert, but if you're traveling all that way you might as well have a place lined up to "hang your hat" for a day or two and relax!!! Plus, then your Tropic/Mayan Air will probably be arranged for you and you won't have to worry about airport transport to your spot.
i.e. this is a VaKay long coming for the two of you... after that feel free to roam as you please.
However, to each his own! Hope you have a fabulous time in Belize. We'll be there in May, and likewise haven't been on a vakay in years![email protected]
