Seconding both. Arizona Grand Resort has a state-of-the -art water park. and the Princess has a ton of tailored-to-children activities and would be my top pick.That's one place where you get your money's worth for the resort fee if you have children. How many children do you have? The Privado studio rooms sleep 5 and don't break the bank (at least they didn't when I was there in 2017)
