I'm planning a 5 day trip in December 2013 to either Scrub Island or the Ritz Grand Cayman. I'm mid-30's, single, and will be traveling alone. Not looking for crazy night life or scene, but would like for there to be some worthwhile evening activities available. I scuba, snorkel, run and hike, and would like to do all of these without much hassle. I'm also interested in local cuisine. My biggest concern is Scrub Island may be too isolated, though GC may be too commercialized... a Goldilocks problem. Cost of food/activities/amenities is not a concern. Any thoughts would be appreciated.
