We chose Summit for our 2002 Alaskan cruise too! This will be our first time to Alaska and our first time on Celebrity. I am soooo excited.
I've been to the Caribbean 4 times so Alaska will be a nice change. Everyone says it's breathtaking. There was even a PBS special on the Trail of 98 and the White Pass Railroad...looks like a beautiful excursion and very interesting too.
We have been spoiled by Holland America, but fellow posters seem to indicate that Celebrity will meet the same expectations. I'm looking forward to a little more upbeat atmosphere and the butler service!
