I know you can go to like expedia.com and from there you can choose a vacation package and then select that you want it to only show all-inclusive packages.
Personally I love the Sandals resorts. They are VERY nice. This is who my family and I go through when we go on vacations.
I have been to Sandals Royal Carribean (Jamaica) and Sandals Montego Bay (Jamaica).... In two more years my husband and I are going with my mom and step-dad to the Sandals resort in St. Lucia. Go to
www.sandals.com and you can choose from any of their great locations to look at pics. of the resorts. They have them in Jamaica, St. Lucia, Bahamas and Antigua.
They may be a little more pricy than other all-inclusive resorts but it is well worth it.
Go and chek it out.
