Destination wedding ideas?? a lot of hotels have free wedding packages included.. but where?? ?

Tons of hotels have free wedding packages included for destination weddings... Bahamas, aruba, jamica...so we are looking for the perfect place with the perfect price.. AND it must be a kid friendly hotel.. So no sandels cause they are for couples only... :( ...we will have a group coming too.. As of right now there are 20+ people coming .. Are there group rates for some places with that many people coming??
