Reserve a shelter so you and yours can be in an area more desirable.
Go ahead
I'd say it is a good idea to reserve just in case...better to have it guaranteed than show up and all the pavilions are being used. That being said, it is August...not sure how many people are doing outdoor gatherings as it is a bit warmer than usual. Oh wait...I might have misunderstood your question....you are allowed to use the pavilions without reservations or paying. The only downside is that you could show up and people are already using it and your party plans will need to be adjusted. Does that help?
