I LOVE Bermuda! I could write a book on it, but many have already been written and it's well worth the 15 or 20 dollars. It's just the best of both worlds. It's a crusie, but you stay the night, so you don't have that rushed feeling. The bus system is so easy. The beaches have the beauty of the caribbean without the 'braid your hair lady' beach hawkers.
There's a quirky little beach called snorkel park right in King's Wharf. The snorkeling is truly amazing. It's a great spot to walk over too after you're hot and tired from a long day. Crystal and fantasy caves are amazing. The glass bottom boat tour is phenominal. Plus all the adventures that Sandy mentioned. The tough part is deciding on only a few!
