We are a family of 4 and have one DD under 10 (she's turning 8 soon). I was going to try to buy a few of these- if I can snag a few at the end of the month. (3 days for $87). I'm going to try for atleast 3. What about the 8 year old though? Is there a cheaper way to get a 3 day ticket for my 8 year old? TIA!
