I can help you spell Aruba correctly but that's about it. As an aside, I wouldn't pick an island to vacation on based purely on which of two hotels is nicer.
There are worse mistakes than picking based on hotel. The hotel may make up the majority of the trip. That being said I recommend tripadvisor and then looking for random itineraries online to figure out which destination will make you happier.
Which sites would you recommend for sample itineraries?
every destination is different. I usually google 3-5 day itinerary to XXXX
