Yes. If you are Gold Elite, you should get all the benefits that a Gold Elite normally enjoys at that property. As mentioned, the benefits can differ by property, for example many of the resorts do not offer free breakfast, but in general you should be treated like any other gold elite which means if the property has a lounge you should get access.
I would just be careful to check what benefits the specific property you want to redeem at offers Gold elites. The Marriott Lounge thread is a great resource for explaining what elite benefits each property offers.
