I personally like Islands Magazine. It's a great magazine that highlights properties across the Caribbean from value to luxury resorts.
Click here for their picks for best all-inclusive resorts.
I was so excited to see Couples Tower Isle on their list.
This resort offers free wifi. It has an offshore private island that allows nude sunbathing. For activities, they have catamaran cruises, glass bottom boat rides, a Dunn River Falls Tour, and beach volleyball and tennis. They also publish an incredible social schedule every day with dance classes, bonfires, karaoke, and more.
The best part of this resort is that during the summer, you can get there for a week for under $4,000 per couple. Email me at firstname.lastname@example.org to book your romantic getaway today.
