Priceline and Hotels.com dont have options for suites. How did you book?
My experience has been that connecting rooms are not guaranteed and depends on availability at time of check in.
While that is true, I've booked countless connecting rooms and only once didn't get connecting. So my wife and I slept in different rooms that one time. Big deal.
Is it a bad idea to book a regular room and only say I have 2 adults and show up with 3 kids with me and try to get upgraded to a suite by a Marriott residence inn? I have gold status
