One of the favorites for the kids is swimming and this weekend we took them to one of the local recreation center pools that also has a water slide and splash area. For the four of us the total cost was $16. Check before you go but, some of the smaller water parks and pools will allow you to bring in your own food. We brought drinks, sandwiches and chips. This week we plan on going to Hawaiian Falls, there are three in the Dallas area; Garland, The Colony and Mansfield. The offer several package options and they allow you to bring in a cooler (always a plus!).
Movies are always fun but, can be very pricey. AMC is having a "Summer Movie Camp" and these $1 movies for charity are from June 17th through August 5th. The shows are every Wednesday at 10:00 am.
Specially with children they need to feel secure and normal and they don't need to be worrying that you do not have money for this and that. So, I hope that this has given you some ideas of how to entertain and have fun on the cheap.
