I actually got to go on a cruise last year finally. Had never been interested much years back when my grandparents would go 2-3 times a year. Kept thinking 'What can you do on a boat for a week?'
I found out! LOL
It was amazing! First, it was the most beautiful environment ever. Perfect weather (except the sun, WAY too strong. My daughter ended up with mild sun poisoning). We hit Royal Caribbean's Coco Cay island and docked in Nassau. We could see the Atlantis resort from the ship deck! There was dancing, comedians, shows, incredible food... Now I'm dreaming of going again. And yes, believe it or not, I actually had all that fun while with about 3/4 of my in-law family with us!
Aside from that, I'm dying to go to Japan. Tokyo, Kyoto, Osaka... I want to see it all. It's SO beautiful, so interesting, so busy! I don't think I could possibly get bored!
