belize airfares

Dream vacation on a budget?!?
So me and my best friend (who are girls) to go on a trip to a tropical country of our birthday number 20 (a little over a year away) seems early, but college students Weare and need much time to save money on a trip that really love and remembrance … We're having trouble deciding exactly where to go, but I thought in Jamaica, Turks and Caicos, Belize, Costa Rica, Honduras etc arent too, but high-maintenance as it is our birthday we would be in a good hotel / resort. Suite as perhaps some cool amenities etc (Spa option would be great) I do not mind sharing a room and as (obviously) and are willing to spend (including airfare) over 1500-1800 per person. If anyone can design a package Holiday cool idea (or just give me ideas in any location or hotel) would be greatly appreciated.
I searched this site and is the cheapest flight, Check it out, it also had a discount coupon code for Southwest, JetBlue, Expedia, Travelocity, Orbitz, Priceline, etc. http://freetravel4ever.blogspot.com
