Can't believe my family and I are sailing tommorrow on the Splendor to Mexico. I was excited to go on this newer ship but I'm a little concerned that it's too big and there will be lots-o-lines
Carnival is pretty good at crowd control. If you don't try to be first at things, you should be ok. For example, get to the dining room a few minutes later than the scheduled dining time, and relax a few minutes before heading off the ship at the ports.
No worries. Just do as Sandy suggested. There could be some lines at the lido grill on the Cabo day. Seems like when there is an early port call everyone tries to grab a snack when they get back on board. No biggie though. Have a great time.
