I'm thinking of booking 3 nights @ OKW with 7 nights MYW tickets with free add ons and then using pin code for $139/night @ Riverside for remaining 4 nights. So far I've booked the pin rate for 7 nights but plan to book MYW and then revise 7 nights on pin to 4. Will I have any problem revising reservation with pin? I was unable to book a moderate for 5/6-5/13 with MYW plan special, so I thought maybe this would be a nice way to try a new resort (OKW). We need park tickets and plan to do DQ and a water park. I've never split a stay but thought maybe this would work. Any suggestions?
