It is an awesome time to go, the weather is usually great and the crowds not too bad. We have done that time twice and our next trip will be around that time again also. Enjoy!
ABSOLUTELY,
We always go at least two weeks after Easter, and it is perfect!!! No spring breakers, pretty much all of the k-12 spring breaks are over too - and the weather is always beautiful (at leat it has been for all of our trips in April). We took our three children last April, and it was just the best trip ever. Low crowds, great temperatures, perfect!!
