As a PP, you're officially entitled to a free (standard) suite upgrade at RCs, based on availability of course for your entire stay. However, you're not entitled to club lounge access without paying extra, although the hotel is free to offer this on an above and beyond basis.

If the hotel has separate club floors, is there a standard suite available for your stay on a nonclub floor?

Otherwise is there a standard suite available for your entire stay?

It's unfortunate that your reservation showed the exceedingly generous preupgrade, but unfortunately the hotel is not obligated to provide such an upgrade, even if available.
