Hey -- Congratulations
I would contact your destination concierge as you may want something reasonably close to the location of the wedding and as well the concierge there will be very knowledgeable. Otherwise let the folks here know where you will be located and I am sure additional suggestions will be forthcoming. I know of a nice place by the Renaissance Ocean Suites and with the two Marriotts there, and being downtown, would bet that you would have your choice.
