Hi Disneymom1...we also have 2 elementary age kids that travel with us and you are correct that you are only guaranteed sleeping for two.
In our priceline experience, and we have a fair amount, we have not once (knock on wood) had any trouble at all getting a double queen room. We don't even have to ask. When the desk personnel see our kids they say "You would like a double room?" Of couse we say "That would be great."
We have stayed at fabulous places in: Miami (Sheraton Bal harbor, resort), West Palm Beach (Crown Plaza, 3 star), Clearwater Beach ( Hilton, 3 Star), Orlando (Renaissance World Gate, 3 star), Miami (Embassy Suites, 3 star).
BUT, I am the type that doesn't get bent out of shape if things don't go acording to plan. I consider it a challange and deal with it. I am not sure exactly what I would do if I was told "we have a one king bed room for you". I guess we would all sleep in the one bed.
