I do believe the Hollywood Beach Marriott still has a lounge (and elites do get access.)

For me, when traveling with the family, I'm usually not as enamored with stuffing 4 or 5 of us in a single hotel room even if it is on the beach. I normally try to find an MVCI property instead and get a big suite with a full kitchen. I've stayed at the MVCI properties in Ft. Lauderdale, Aruba, St. Kitts, Hawaii (more than once), etc. All of them were on the beach (OK, the Beachplace Towers is across A1A, but as close as it could get to the beach there. ) I've not tried it yet, but the Marriott Key West Beachside hotel is really an MVCI that Marriott turned into a hotel instead. So lots of 1, 2, 3 bedroom suites for awards.) In all of those, we tend to buy some breakfast foods and cook breakfast in the room every morning. Much cheaper and is as tasty as we want it to be.
