We took the Wish in January. I thought it’s the newest/biggest.Have done one, first cruise as well. Wedid the Wish out of Miami for 5 nights.
Plus points:
Disney does things well, I've no other cruise to compare but between food, areas, kids entertainment.
Kids area - if my daughter was a year or 2 older we'd have let her run her entry/exit. Great place.
Food - again, no comparison but it was really good.
Photo package - buy it, worth it 100%
Negative points:
Cost - mickey knows where your wallet is.
Wish boat - oldest, smallest boat, adult area was not adults only, smallest pools, most crowding (that's how I felt)
Disney overload - the constant Disney is too much, we know it's a Disney cruise, just didn't expect 24/7 everywhere you walk.
