If you booked at 1800Hotels.com, call the hotel and check on your reservation immediately.
They filed for bankruptcy in Florida last week. I found this out because my DW asked me to call our hotel in Barcelona, where we are staying one day before and after our cruise, to make sure we are getting the corrct size room four our family and found out our reseervation was cancelled.
We were able to rebook on our own, but at a higher rate.
I also called our credit card company ad they will be refunding our money.
For some reason, this hasn't received much press in the US, but has been in the news in Ireland (where the parent company is also having financial problems).
Had my wife not asked me to check, we would never have known until we tried to check in.
The website says nothing about the financial issues and there is not answer at customer service.
