Thanks for your replies.
I wish that I had spoken to a manager about my problems while I was still at the property, but 1) I was feeling non-confrontational at the time, so when the front desk clerk had nothing but smiles and apologies, I let it go, 2) I didn't see a comment card otherwise I would have immediately filled one out, and 3) it wasn't really until after I left the property and stayed at other hotels on the same vacation that I realized how truly 'ripped-off' we got. By way of example, our stay following the FS Santa Barbara was the Beverly Hills Hotel. For $125 less per night, we got: a non-upgraded room that blew away the FS in every way, a bathroom that was 5x as large and infinitely more comfortable and luxurious, and a breakfast allocation that actually didn't cause us to spend additional money just to get 2 traditional egg breakfasts (unlike the FS Bed and Breakfast package). Sometimes it takes a like-comparison to put things in perspective.
I'll post my letter shortly and keep you apprised of any consequences.
