True, Best Western Park Place Inn and minisuites has a room with 2 queen beds and a full size sofa bed. The vanity area is outside the bathroom so you would be able to get ready easier too, also a larger fridge and a microwave.
But...how old are your children? Don't say I told you this but we know lots of people who stay at the DLH or PP with 6! You just can't "Say" 6! You can get a room with 2 queens and a daybed and then ask for a rollaway too and all 6 can have sleeping room. Also, it one of your kids is crib age, most of the rooms already have a portacrib in the closet or you just call housekeeping to bring one up (along with the coffee maker!). Rollaways are free but no micro and a small fridge. Just don't all stand there when you check in! Plus your parents might qualify for the senior rate which is sometimes 30% off!
