If you would like more input about the summit, I would suggest posting on "Know Before you Go," since it will get more hits; I don't think as many people read these messages as often.
To get there, click on "forum list;" then click on "Know before you go."
I have never cruised Summit, and am cruising our first Celebrity ship in Jan (Constellation), but have heard all good things so far. What type of feedback have you heard, and where did you read it?
The reason I ask is b/c prior to our cruise on RCCL -Explorer, I read many very poor reviews on cruise reviews.com, and was worried about our choice. Keep in mind, my husband and I are pretty critical about service, cleanliness, amenities, and overall experience when it comes to spending $$, and our experience was PERFECT!! So, take them with a grain of salt. That's why I like this forum, b/c you are simply asking for opinions; on those "review" sites, that's where people will go when they want to complain b/c they had a bad experience that 1 out of thousands may experience (if that!).
Just my 2 cents...Good Luck!!
