Thanks for the help in this thread, Socrates! Speaking of the VIP rate again I found these rules:

What is the VIP card? Who can get one and how? I noticed that this was one of the only codes the Springhill Suites (Montreal) would take. The code offers a nice discount.

Also, when I tried PKG there was a rate called "Spa package" that was a few $ higher than the rate I now have. I wonder if they include something extra?
