If you are a parent of a young child (3-10), Plaza Fiesta's play area should definitely be on your list as a place to take the kid(s) to burn off large amounts of energy. For only a couple bucks kids can play on a 4+ story play set with large slides and tunnels for a couple hours in a secure, fenced/gated area.
Within the enclosure there are plenty of chairs/benches for parents to sit and watch, read, or peruse Facebook & Yelp :)
Outside of the play area there is a decent video game arcade, and local restaurants to eat at. All and all a nice spot to stop by for a couple hours to let the little ones burn off the energy and wind down.
