The ITMB Travel Map of Belize is a necessity, whether you are driving yourself or have a driver. At $8.95US it seems a bit pricey but it is NOT! It is well worth the expenditure and is available all over Belize.
An alternative to fussing with a vehicle and finding your way is to hire a driver and his car. Add up your cost of vehicle per day, fuel (much higher in Belize) and frustrations and you might want to consider.

and I'll give you the name of a great driver whom I have used many times. Unless, that is, you are going to be there January 6-16, 2001 when we will be in Belize also.
