I suspect there are two or three layers of discrimination.
There's probably a bit less overt racial discrimination now than there may have been in, say, the 50s, though what's left sets you up for the next two layers.
You're going to have be judged (by hotel security) as "the right sort of person". This is clearly open to all sorts of discrimination (race, age, gender, social class, genetics and more), but I suspect that if you don't actively violate someone's mental model of what they want their poolside to look like, you might be OK.
On top of that, you'll need to be able to spend money. This is not a coffee shop where a single americano gets you a seat for the day. If you're not regularly ordering drinks and food, I imagine that hotel security is going to ask you to move on after not that long.
