Just off MV, happy to answer questions. We were 2 adults and 2 young adults (20 and 22). Less than 100 kids on the boat and the rest was not to capacity. With our dynamic we didn't do any of the kids clubs though my kids went in Vibe and said it was cool, but smaller (with no pool). I agree here the Quiet Cove was overrun with adults but this was a weird cruise so I think that may settle out over time. That said I did enjoy the area everyday, people will share their sitting area so if you want to be by the bar and pool just wait a few minutes. Food is crazy good! The MDR are so good! The quick service BBQ is ridiculous good and the pizza is great! There is a taco/bowl area that seemed to be a hit because of the line but I didn't try it. 1923 MDR was my favorite but then I'm a little over the shows at dinner.
Agree the layout is confusing since it is a completely different layout but I guess we will learn over time. Things are more in 'pockets' rather that areas. For example no adult district anymore just random bars around places (and yes they all close at midnight except for Bayou which is 1am) I still shake my head that they close down and leave adult money on the table, there were adults everywhere and they still shut it down. Oh well.
Luna is the 'new' Tube so thats where variety shows are. Get there early. Its not a lot of seating.
Lastly, we were one of the familys (400 ppl!) that were going to do a b2b but our son tested postive (as did about 100 other people that were going to do b2b) so a full refund lately we were driving home and missing our DVC 3 night cruise.
DCL was completely overwhelmed with how many tested positive they said they have never had that many people test positive. 20 staterooms they had to get luggage from and bring down to people. I was just glad we drove because if you were flying they put you up in the Hyatt for 10 DAYS?!
Ask away!
