This year and last we have found a way to do something fun with the family of 8 relatively cheaply. We buy 4 season passes which come with coupon books that have several "Bring a friend for free" days. We had two bring a friend for free tickets that we needed to use for June. So, we did two days in a row at Six Flags and then went to the Arch on our way out. My brother and sister-in-law were nice enough to let us crash at their house for a couple nights. Uncle Ronn took some time out of his busy schedule to ride some rides with us on the second day. The temperature on both days was at or near 100 degrees. So, we spent a good deal of time at Hurricane Harbor.
Stopped at Burger King to fill up our tanks and avoid a costly meal in the park.
