I linked Marriott and with a newly created SPG account. Do I also need to create and link at Ritz Carlton account and does my status transfer?
Ritz Carlton is already part of Marriott so you do not need to do anything specifically for Ritz. Keep in mind however that being platinum or gold with Marriott doesn't get you very much at Ritz Carlton hotels. For example, no free breakfast and no admittance to the CL unless you reserve a room that specifically allows access to the CL.
