I'm probably looking for suggestions here. My wife and I are old folks that like to sit on a beach and also snorkel. I'm gonna list my top 10 and then see what the rest of you folks suggest. My list will be very heavily weighted to the Philippines since we have spent a lot of time there. I know some will suggest Phuket. That is a bucket list location if we ever get back to Asia. A relative is the Mission President in Thailand right now and we would love to go before he comes home in July. But, you know, covid.
1- Siquijor, Philippines
2- St. Lucia
3- Kauai
4- Boracay, Philippines
5- Roatan, Guatemala
6- Grand Turk
7- Panglao Island, Bohol Province, Philippines
8- Grand Cayman
9- Palawan, Philippines (We haven't been to El Nido and Coron which if we ever do will probably move this one higher)
10- Aruba

Just off the top of my head. I'm sure I'm leaving some favorites out. I'm bored, can't play golf, and no Cougars until tomorrow. (Hopefully)
