Oh, the vicarious thrill of a Priceline bargain. The noise thing happens all too frequently. Very very common now in the Washington DC hotels with the high school trips. The better hotels hire Rent-a-cops for these trying times. The others do nothing.
Calls to the front desk rarely brought results. Calls to my credit card company did (dispute the TOTAL bill). Usually the only peace is on the concierge levels if you are lucky enough to get there, but moving at 200am is no picnic.
Many mornings I have awakened to fire extinguisher residue all over the hallways and/or food party junk or the wonderful aroma of beer/pizza/hamburger vomit from an eighteen year old on his/her senior trip. Ugh!!
Again, call or write your credit card company ASAP and dispute the charge. I received full credit each time for non-Priceline stays (I dont do Priceline).
As for a "free weekend".......this doesnt cut it (or solve the problem).
