Just sailed on the Imagination last month (on a B2B) after the Evolutions of Fun upgrade.
Sadly, there are no hairdryers in the standard cabins (I don't know about suites). However, there is everything else you will want or need.
It is a good size ship (not to big...not to small)....
They have the new Adult Serenity Area...one deck below Lido AFT.
They have the new kids waterpark...one deck above Lido AFT.
They have lots of food options out by the pool along with the buffet, deli and pizza inside Lido.
Melvin will be your karaoke host and he is WONDERFUL.
Club 02 has their own space (if you have 15-17 year olds)
Circle C (12-14) was working on their own space when we were onboard.
Jorge (CD) is precious and a riot!!!
Noonan (ACD) great.
Jamie (Social Host...who should be an ACD soon) is FABULOUS!!!
I think Steve will still be in the piano bar. (I don't think he leaves until May...but not positive about that). He was a lot of fun.
Great staff....good food...good entertainment. What more could a person ask for???
Have a great cruise!
