I will get back to you on that- need to double check amount needed these days
Though Colombia is a more expensive country for Food, Hotel, Taxi, and all the basics.
The flight to DR is cheaper and the hotels are cheaper, so the 50-60 TLN or 30.00 ST is not that bad.
MP's are about 25.00 with BBBJ and the top of the line MP's are more like 50-60 with two girls giving bbbj and massage.
But on the whole, unless you plan on gambling or doing major deep sea fishing and surfing and shit there is no way you can even come close to the 2800.00 amount. Much less than half that if you are just going to drink, p4p and hang out.
The biggest problem most guys have with the DR is that they run out of money because they bring 1k and drink all day and night for a week. They still have enough to fuck every night and make it back to states though.
Avoid tourist traps and american owned ripoff clubs and 1500.00 will last a week including airfare and hotel. If not more.
