Claudia, it sounds like your neurosurgeon is definitely helping you prep. for your venture

.
If the cruise people (what do you call the people who run the ship? hmmm) have transporter chairs on-board, I hope you'll consider that. Keep as much strength and stamina for enjoying your trip as pain-free as might be possible

. I'm sure you know that, though, but a gentle reminder... well, that can't hurt, huh

.
I take my chair most everywhere - afraid that one won't be available (due to demand) when I go out, though it would make going out much easier if more chairs or even more places provided DME for customers' use.
I've not been on a cruise, so I'm looking forward to
your trip. You're gonna have to give us the scoop when you return from it!
