Yes, this is the week before Easter. It falls on the 20th this year.
We were in FL around that time last year and weatherwise, it was fantastic. It only rained one night and it didn't start until around 8 PM. We were there for 10 days.
We didn't have Easter crowds to deal with since it was early last year, but it was NH & MA school vacation weeks. It was crowded but very managable.
