I would go for 2 rooms. This would give you 2 bathrooms which would make it easier for getting ready in the mornings. It will take a lot of time for 4 adults to get ready in the morning with only 1 bathroom. Also, this would allow the brother and sister to have their own bed. I love my brothers very much, but I wouldn't want to share a double bed with them.
I think 4 adults will be fine at Pop.
Just remember there will be a $20 a night extra charge a night for the extra adults. ($10 a night for each adult after the first 2)
If you are going Dec. 1-14 and can stay Sun-Thur night you would be able to rent points from a DVC member and stay in a studio @ OKW for as low as $90/nt -- you'd have two queen beds, a kitchenette, and a lot more room!
I think it is, but it might depend on the size of the adults. The beds are only full, not queen. Bigger guys might have issues. When we've done this, I usually will sleep with DD and DH gets his own bed.
Yeah I wish I could get codes. I get them all the time in the mail but they are for the previous owner and we have lived here for 4 years now! Plus the previous owner never went to Disney before. Go figure.
As far as only 1 shower 2 can shower in morning an 2 can shower at night that speds things up as well or there is always the mid day shower. Every one shouldn't have to shower at the same time.
There is also a bathhouse down by the pool they are usually very clean DH likes to sit on toliet to long of a morning I have sent him there to do his morning ritual.
DH and I are both pooh sized we have no trouble in a full sized bed together. Yes we prefer a queen but the full size does work. After the 1st night we so tired all we want is to lay down. The big thing for us is to make sure we sleep on same side of bed that we do at home. Actually at disney that prolly not an issue after the 1st night either.
