We've been in Orlando since late February and are at our third resort with one more to go later this month. We've heard the same thing at all three resorts. March is crazy busy this year and it will be this busy until after Easter is over.
You can only post the same thing once so I picked the first listing I saw to post this on. A heads up to anyone looking to come to Orlando in the next few weeks. You probably shouldn't expect to see a lot of availability nor dirt cheap prices this year.
