Hi troostdental, welcome to Cruise-Chat. Please take me with you and your wife, I'll be happy to do the laundry.
Seriously though, we've never been on any longer cruise than 21 days. I have been praying that I can save enough to one day do a world cruise. I can tell you that 21 days seemed like 5, I was nowhere near ready to leave the ship. We were only in the Caribbean, so I can only imagine being in different parts of the world. It would be so exciting. If you've ever seen the Travel Channel special on Residensea, I guess it would be similar to that experience. That's the ship where you purchase your suite and live on board. There is on board internet available, although it is not like broadband, similar to dial-up speed, so keeping in touch with those back home might not be so bad. As Cruise Fanatic stated, in an emergency, you could be contacted. Congratulations on your retirement and what a way to celebrate!
