Yes, it seems they are selling those suites really well. I don't have the exact numbers but they do have a healthy amount of suites in total. maybe 90-ish. So maybe 25 of those are the Grand Habour Corner Suites and then another couple dozens suites across the "non-corner" harbour view categories.

But yeah, this is one hotel where I would really push hard for a suite. Typing this from the Manor Club and still very impressed at the quality of the food and staff here.
Today was day #2 and just about 75% of the staff in the Manor Club addressed me by name. Was not expecting that.
