St. Paul, Westin or Opus hotels? recommendations for bachelor party?

[dolla billa]

we are doing a bachelor party in mtl and are looking at the St. Paul Hotel, Westin and Opus.

we are planning to rent a penthouse suite for a show and for the bachelor to be entertained.

just wondering if anyone has been to or has any feedback on any of these hotels or penthouse suites.

thanks.
