Jeannie Gee owns Shop n Drop and she is awesome.
As for the groceries and restaurants, I don’t know the hours but you will be able to get groceries Easter weekend ( though I personally would book through Jesnnie....) and the restaurants island wide will be open. Perhaps not all but you won’t go hungry.
The only thing we ever had a problem getting that close to Easter was candy for the bunny to leave for the little ones so if you need those types of things, best to bring from home.
