Be aware, much of the park has paths where bikes are not allowed. Give yourself time to park bike and walk to explore, take the bike locks with your rentals. Expect a lot of bike, bike trolley and foot traffic. Foot traffic was the biggest problems, runners too close to bikes and people crossing the path right in front of you.
Bike store was fine, but don’t expect friendly attendants or bikes that are well maintained. Good price and convenient location, but there are rentals right inside the parks also that are closer. I wanted to like this more, but it was just ok.
