I just retired at 69yr. Female, 3 cruises. I would like to share expenses out of Tampa since that is where I live. I haven't seen to any of the Maya ruins yet. Looking at Royal Caribbean on Grandeur of the Sea. Sounds like an interesting job that uou have. I like being on the computer a lot but am not a geek. I used it a lot at work and got used to it's value. Love paying my bills on line which scares some people.
Good luck with finding a room mate!
