I agree that it's all what you were used to. DH and I used to have a queen and it was tight, but doable to sleep in the full bed. We got a king at home and, since then, it's been hard to go down to a double bed. We usually end up with an adult and a child in each.
On our most recent trip we rented points and stayed at OKW. The queen beds were heavenly. I don't think we can go back to doubles.
