I think if you give a little more info for what your needs are it would be easier to suggest a place. Starting with Budget....then what your "must haves" are....like beach, watersports, shopping, food, etc.

There are not any AI resorts in the PR like what you will find in Mexico and Jamaica. There are a few hotels with AI plans.

The DR is one of the areas like Mexico and Jamaica known for their AI resorts. If you liked the Iberostars, that chain is in the DR also.

Also, look at Cozumel. Great bang for your buck. Cute town and great snorkeling.

We need to know how "limited" your budget actually is. You see those types of terms ("limited" "affordable", "most bag for your buck" are meaningless unless we have a dollar point of reference. we also need to know of your budget includes airfare or is it just for accommodations.

Lot's of AI's in the Dominican Republic, Cancun, Cozumel and Playa del Carmen so begin your search there.

If you're looking at lower priced All-Inclusives I would start with Punta Cana DR, Negril Jamaica, and the "mayan riviera" of Mexico around Playa del Carmen.

With such a short vacation I'd also consider where you can get a nonstop flight (if anywhere).

For 4 to 5 nights, Grenada might not be practical. We're in Boston and love Grenada, but getting there is a pain from here.

Head south young man... er woman. Personally I find the more northern islands too cool in the dead of winter. The water is cool and the wind can be downright chilly. For a limited budget and ease of travel from Boston (I'm in Boston, too) I would look at Aruba. It's far enough south to find warm air and water. You can sometimes find a direct flight and it's one of the less expensive islands. There's a huge variety of restaurants to fit every budget and you can often find reasonable air/hotel package deals.

Though I love Aruba, I have to disagree that it's one of the lesser expensive Islands. Air and a regular hotel package from my departure airport in Texas runs double + for what I can get an AI resort and air for in Mexico. Then you have to add on food and drinks in Aruba. They only reason why we have not returned. It's also a 5 hour direct flight from Houston, while Mexico is only 2 hours. Aruba really needs a good 7 days or more due to the long distance.

I know you said you have already been to Jamaica, but look at the Jewel Dunns River in Ocho Rios. A much different area and a great couples only AI. We stayed 5 nights last December and got a great price. Pools and ocean temps perfect for swimming, and the weather beautiful. We really enjoyed our stay.

However, depending on what your "limited budget" is, I still contend Cozumel would be your best bet price wise.

I agree with KVR on most what he said. however flying from Boston to Aruba non stop is about 4 hours or so. not so bad. I doubt you will go any place in the Caribbean for less time providing it is non stop of course. Difficult from Texas to get non stop but from the east coast easily done--for a price! Other than that Aruba is not always so cheap although you can eat cheap with typical chains TGIF Wendy's etc. if that is what you want. I would try to look into applevacations.com and see what they might have in package deals. Mexico, would be my first choice for al AI I am not a fan of the DR but for the time frame and price you might get lucky there. Your time frame is high end season. Also check into cheapcaribbean.com People are saying they are finding great deals there but do try and get non stop for 5 days. good luck.
