After our last trip to Orlando my family and I really enjoyed our time at Universal and vowed to spend some onsite time here on our next trip. I booked the Harry Potter Package which I thought was a pretty good deal.. $1000 for 5 night dec.21-26 ..but after our DVC dates were confirmed I wanted to move up our Universal stay.. I thought if those were their holiday rates it wouldn't be a big deal to change it to dec.24-29 instead.. but this change would result in a $1250 rate increase!! What!?? With our first reservation at $200/nt I was considering changing the reservation to 9 nights.. but not at that price!!.. I questioned the woman on the phone but she said she had no idea why it was higher and she couldn't tell me what day or days were making the difference.. I am hoping someone here can shed a bit more light on what dates I should pick to still get a great deal.. thanks!!
