The most important hotel benefits are:
breakfast
room or suite upgrade
club lounge
parking and resort fees
RC does not offer any of the above to most Bonv^y members. Titanium and Ambassador may get something. I think the SNA may be used, not sure about it.
When we stayed at RC Dove Mountain, we paid resort fees with parking included. The room was upgraded, but at hotel's discretion. No breakfast nor club lounge. Same with RC Cancun.
