Having cruised twice recently with Celebrity,  I really like the Solstice Class ships.  They are modern and sleek.   The lounges are warm and inviting.   My favorite spaces are the Sky Lounge, (fantastic ocean views), the coffee bar (a great place to chill and have a specialty coffee or tea along with a dessert or read a book), and the lawn club (great place to relax or watch the glass blowing show)  The food is good to great depending on what you order (last night was Beef Wellington and lobster YUM!).   The crew is friendly and attentive.   We were in a Sky Suite last cruise and well worth the price if you could afford it, this trip we are in an aqua class veranda and personally I don’t think for ME it was worth the extra money.  I would book a veranda next time and save some money.  The lawn club is awesome.   The only complaint I have is some to the spaces they use for Bingo and trivia are not large enough to comfortably hold everyone that wants to participate.   Entertainment has also been good.
