The hotel does not rent out beach chairs and umbrellas unfortunately. As everyone else has said, there are plenty of vendors on the boardwalk and right outside the hotel that will rent those items to you.
There's a beach umbrella/chair rental spot directly outside of the walkway from the hotel to the beach. I am not familiar if the hotel itself actually provides anything though.
A third party vendor rents chairs and umbrellas outside the hotel. I'm not sure if it's seasonal or year-round. It is fairly steep price wise.
The rentals the folks here talk about are, indeed, available, but not cheap. You can pick up some chairs and an umbrella of you're own from a beach store for less if you will be there more than a day.
Not that I am aware of. But there is a place outside in front of the hotel that rents umbrella and chairs.
