I was planning a multi-city stay in Europe (London, Berlin and Barcelona). Due to some cancellations, I am dropping the Barcelona leg of the strip. I made a reservation at a Renaissance hotel in Barcelona that was "non-refundable if cancelled after 1 business day;" that deadline is passed.

Is it possible for me to convert the payment I made on the Renaissance Hotel into a deposit on a Marriott hotel I am using in London (Edition)? I have no Marriott status and have not made any prepayments on the London hotel as of yet
