I am currently in the midst of 40 days in Marriott's around the DC area. I'm moving a few times because my work is sometimes VA and sometimes Bethesda based.
Today I moved into a RI in Fall's Church because I had some writing to do, it was in the 90s and I wanted to do it outside by the pool. The pool area is beautiful on the website....and also closed for the season (??really, Sept 2nd in DC with temps in the 90s for another few weeks??) without any way of telling from its nice feature on the web site. That irked me when I realized it a few hours after check in. So I decided to take the advice of the thread... log on to FT and complain about something this minor.
Seriously - if you pool is closed for the next 9 months in a summer climate, quit featuring it on the hotel homepage.
