NO WORRIES!! The Dream is a BIG ship!
We were on her two years ago at the end of February. Not only did many New England schools have vacation but it was also around Mardi Gras so there was a huge contingent of New Orleans area folk who had a break that week too. I'm pretty sure it was a sold out ship too and had the same

thought.
I was pleasantly surprised- other than the sea day when the pool area/deck was mobbed and the night of the pirate party when the deck was mobbed again and movement was limited due to where they were shooting off the fireworks- I didn't notice it much at all. I DID expect it to be bad- waiting for elevators, dinner taking longer, long lines to get into the shows but was pleasantly surprised- we didn't encounter any of that stuff.
As Crush says...just go with the flow and it will be a great trip!
