To Hubby of slenderella:
1) You only have to pay once per day.
2) Just show the receipt at the next parking lot and get in free.
3) However, don't let her know.
4) Hold the cash and receipt in one hand.
5) As you pass through the gate, simply "palm" the cash.
6) It will look like you paid.
7) She won't even know, and you get more Mad Money.
NOTE:
This is kind of like not wanting to ask for directions.
If you call it exploring, you are never lost!
PS:
I have been known to do A LOT of exploring.
