We just returned from our lovely 14 night cruise upon Celebrity Solstice. It's our 3rd cruise, the first without our kids! (we are aged late 40's early 50's). Here is a summary:
Embarkation: Pretty easy. The line looked long at it seemed a complicated series of things to do but it still only took 45 minutes in total to board the ship.
The Ship: Absolutely beautiful! It is big, plenty of space despite being at capacity, spotlessly clean. Everything about this ship is classy. The staff cannot do enough for you, so polite and friendly. Lovely pool areas with plenty of comfortable deck chairs everywhere. I really liked the indoor pool, so peaceful. The only slight complaint is there is not really spectacular a 'grand foyer' area like many other ships have. So when they had some interactive entertainment it was very squashy and difficult to see.
