We just got back from Orlando last Saturday (25 Sept) and the queue for the family Harry Potter ride was 60mins and for the older childrens/adults ride (Dragons Challenge) was only 20mins. We found the queues for all rides very short.
Also, we bought our park tickets from a hotel when we got there and now having a look on Undercovertourist.com (gained through the mousesavers.com website), the tickets would have been cheaper to purchase in the UK first. For a 5 day base ticket for Disney, we paid $550 for two adults & for the Orlando Flex ticket we paid $504 for two adults. On undercovertourist, a 5 day base ticket (plus one extra day free) it is $483.90 and for the Orlando Flex ticket it is $485.90, so a good saving on the Disney base ticket.
We didn't shop around for our tickets in Orlando, so not sure whether we could have got them any cheaper over there, but just thought I would post the prices we paid, incase anyone might find this helpful.
We had a fab time and I wish anyone who is going Happy Holidays
