"We thought Celebrity would have a more mature crowd, possibly better food, and hopefully be more professional than some of the staff on the Enchantment."
It will be all of those things Tammi. And not too mature, mostly 35-65, well seasoned travelers. RCL is nasty, IMO. I'm trying my first Princess next month on the Ruby and I only hope it's not too much of a let down from Celeb. I also, judge lines on the quality of the food, service, passengers, etc.
Which ship are you sailing? All M class are great, but some have gone into dry dock more recently than others. I believe Millenium was at the bottom, but THINK she just got overhauled. Constellation, Infinity, Summit, great.
General rule of thumb, stay away from Sky Deck on all the ships - noisy and huge overhang that blocks the view. Other decks are all fine, depending upon what amenities you wish to be close to. If you like to walk one flight down to nightlife, restaurants, Penthouse deck is excellent. Specifically cabins 6110-6114. I've always done the other balcony decks. Don't pay for Concierge Class unless it is very close in price to regular balcony. Same exact cabin. You get fruit,a pillow menu and stale canapes each night. Not worth more than $100 extra.
Ask away....
