Anita,
I just returned with my family from our second cruise since my translab procedure in Sept. 2011. The first cruise was within 6 months of my surgery. The apprehension you share was certainly an emotion I felt. Dizziness is not really my issue but balance an unsteadiness as some have described is. I found the challenges I have on land to be much the same on board a ship...spiral staircases and walking in the dark are not my friends. However, the motion of the ship was not a problem for me. In fact, I had to chuckle at some staggering onboard...I fit right in and in somecases adapted better than the "norm".
You need to do what makes you comfortable with this decision, but I would agree with comments others have already made...wait and see. Keep this opportunity on the table for now. It may be just the relaxing getaway you need to reward yourself.
Oh, and I did get your message regarding the HEI pictures. I'll be glad to email them to you. I have a bunch. Just PM me your email and I'll send you some Kodak moments. I have a variety of photos from Seton Hall and HEI.
All the best ~ schmidtkat (Kathy)
