I am in the early planning stages of a trip to Canada and was just checking marriotts in Ottawa. The three days that I want to stay in Ottawa turns out to be Friday 5/23/14 to Monday 5/26/14, but there is no availability for marriotts in downtown. Specifically, the three downtown hotels have saturday 5/24/14 as Not Available for Check-In: the Courtyard, Residence Inn, and Marriott. While it is a holiday weekend for the USA (Memorial Day weekend) I don't see any Canadian holidays, and a search on Expedia for other hotels on that day in Ottawa turned up plenty of available non-Marriott hotels. It just seems unlikely to me that all 3 hotels are booked solid on that day SEVEN months out.
Does Marriott block "busy" days off far into the future? Why?
Will they unblock it sometime in the future? When?
