Regna D,
I actually got a really nice suite at the Holiday Inn Select, on very short notice, as a result of a $60 Priceline bid last summer. The problem was there were no curtains on the windows in the bedroom, and I saw neon lights flashing all night. I need to sleep in a very dark bedroom.
On the plus side, the suite was otherwise very nice, big and clean and otherwise was well worth it. However, a number of hobbyists don't really like this hotel as much as the other three stars. That is why I made the comment "careful" with your bidding. I know two hobbyists in particular who loathe this hotel and would probably give you their room for free if the bid was accepted by HIS.
The Chinese restaurant at the Holiday Inn Select serves some very solid dim sum, although you will not find the selection that you would have at Le Maison Kam Fung and Ruby Rouge, which are the two most noteworthy dim sum eateries in Montreal's Chinatown (I assume you know the HIS is in Chinatown).
