I've seen people bring their own shade tents, and portable hammocks, I feel like it's quite relaxing, is long as your group is not causing a ruckus, I don't see why not, I'm not sure if you're talking about full size tents, for camping or just for sunshade, I guess the worst that will happen is try it and see..... Weed is legal, so I'm sure hookah would be fine, it's not illegal to smoke that in public is it?
I'm not sure maybe I've seen people smoking weed there tho so I guess so.
I'm not too sure about that one but if I take a wild guess you should be able to.
