Before you commit to any location, do some further research into the area and the trip. Your travel agent should be able to tell you whether your trip will fall during the rainy season (or hurricane season, for that matter); he or she should also be able to check and see if there will be any construction going on in the area during your stay. You don't want to be awakened each day at seven in the morning by the sounds of jackhammers and bulldozers building a new road through the jungle that surrounds your posh hotel.

Ask about any charges you'll incur for changing your dates of travel or your flight times. These charges can add up to a hefty amount, so if there's any possibility of your changing your plans, tell your travel agent up front.
