Is it open in April since it is Easter weekend, if so will there be a lot of venders open since it is a holiday?

It will be very crowded.

As a recently retired Canton employee I can assure you; weather permitting it will be good!

It will be very crowded since this will be last month before oppressive heat if heat bothers you. Besides it is open the 2 days before Easter Sunday

Yes

Holidays do not keep benders or buyers away lol

It's open, and is usually crowded that month.
