Do they have beach umbrellas to rent or purchase nearby?
Yes, they have both. Chairs are $5/day. Not sure how much an umbrella is. It's a great place! Have a great vacation!
We've never rented or bought umbrellas and usually seek shade under the palm trees on the beach or around the pool. A couple of the tables in the pool area usually have umbrellas, and there is a terrace on the 2nd floor which also has tables & chairs with umbrellas.
As previously stated Sea Lord rents beach chairs for $5 a day.
There are several places nearby, within walking distance, where you can buy chairs and umbrellas. One year we got sand chairs at the Publix Markets for $9.99. Wings and Walgreens also have a decent selection of beach accessories including chairs and umbrellas.
