Mermaid.......Can I make a suggestion? When DH and 3 DDs ages 4, 8 and 12, went 5/30-6/4 we drove in from Nashville (14 hrs!) and arrived in Orlando around 4 pm. We had decided we'd save some $$ and get a cheaper room in the attempt to save money. We ended up staying at The Executive Inn on Irlo Bronson Drive. We paid $59 + tax for a small room w/2 double beds. We did not order a rollaway b/c it was an extra $10. 4 yr old usually ends up crawling in bed w/us during the night anyway! Altho the room was ok and the pool and garden area was pretty nice, the A/C didn't work very well and only had a fan to circulate the air. Hubby was able to get the a/c to work but it cut off during the night so woke up about 5 am hot, sweaty and very grumpy. By the time we took showers, got dressed and headed out to Disney and check in, it was well after 12 before we made it to the Parks. The old saying of hindsight being 20/20 is so true. If we were to do it over again, we'd go ahead and pay for the extra night and just stay at the resort playing in the pool or run over to MK for the Fireworks. This way we could have been in the Parks much earlier Sunday morning.
My understanding is w/5 in your family the Value properties will not allow more than 4 in their rooms. Might try to see if you can get an extra night at your hotel--this way you won't have to unpack, pack, move, unpack......... We stayed at POR and loved it.
