We were there in June. We used this policy quite often!
Basically for every one adult meal youbuy, you get up to 4 kids meals free( this includes their drink!) It says children must be present to get the free food. However, after going there two days in a row with all my 3 children( who would rather been swimming), and being the only person in line with children in tow, I went daily for 9 days after that ordering an adult combo meals and 4 children meals( yep, my husband is a child sometimes)without any questions ever!
Basically, we all ate for under 7.00! Can't beat that!
BEWARE-the wait times are terible, the service is terrible, and u are looking at a minumum of 15-20 minutes each day with NO lines . This became extremely more frustrating day by day. However, for 7.00 Icould NOT justify not using this perk!
