Long story, short...Went to wdw last year. 5 of us. We have a total of 12 days left on our tickets. My 2 18yr.olds aren't coming w/us this year. So I have a bunch of days worth of tickets. I booked the FTP for the GF for 7 days,(got a great deal).Called WDTC & explained about all these days left on the tickets I already have, she said room/package is based on double occupancy & I don't have to get the FTP for my 9yr.old who is coming with us. It'll save us approx. $250.00. We decided to get her the full package & use the new tickets, because next year my other 2 girls might want to come w/us and we can save on tickets then. So, if you really don't need to get UPH tickets for everyone in your group,you don't have to with the FTP. Maybe this info. can help someone.
