If you book a suite, it's not at all the same as being "standby" for a paid suite upgrade if available at check in. The OP already picked the suite at the suite price when he/she could have picked the regular room at the price for the regular room. A confirmed reservation should be more than an "option" for the hotel to see whether they can sell what you reserved for a higher price to someone else.

Also, suite versus room is very different from partial versus full ocean view or mid versus high floor, etc.

Please name the hotel. The Marriott down the street comment makes me suspect that this is a place in downtown Minneapolis, where IMO the Marriott would be an inferior (and less interesting/less fun) choice compared to Westin, W. LM, etc. Ivy and Ren aren't exactly down the street from a (FS) Marriott, so they're not on my current list of suspects, and the context doesn't sound like a suite at a RI.
