Last year we went to Savannah and stayed on Tybee Island in an oceanfront condo because we like the beach with the beautiful historic city to roam in. I hear Charleston is just as beautiful (if not more) but was thinking of staying on Sullivan's or IOP to have beach access but drive into the city. Are the islands very expensive for condo rentals? We like to be able to rent several with several families. We are thinking about coming the week before Easter this year. Is there one island over the others that's more convenient for driving into town? Any suggestions would be helpful. Thanks.
