For travel, it's hard to beat the carribean for cost/value.
Belize is awesome, Get out to Ambergris Caye and also do inland jungle adventures exploring Mayan history.
At this resort Cocoview on the Island of Roatan off of Honduras where I used to work, it's around $999 for your over the water cabana, 3 buffet meals a day, and unlimited diving for 7 nights. WOW that's only like $150 a day per person for your room food and fun.
Welcome to CoCo View Resort
and it's hard to beat an All Inclusive resort on Cozumel Island which is right off of Cancun and Akumal.
GREAT travel websites:
Cheap Caribbean
and
Travel Deals: Airfare, Vacations, Cruises, and More | Travelzoo
I just got back from Cancun, where on Cheap Caribbean they have sales for All Inclusive All you can Drink All you can Eat and a nice resort for $39-59 a night per person. Dammmn hard to beat that.
cheers!
