Four Points is old Miami Beach. We were there in January and I'm not sure I would do it again...it is quite a hike from South Beach and the deco stuff. Lots of dark green carpet and garish (read pink/orange/fuschia) palm tree upholstery and bedspreads enhanced with whitish wicker and rather worn furniture. The rooms have that odd FL dank/damp AC feel to them.

The Biscayne Bay is standard convention Sheraton.

Now, the Westin Hollywood, FL is ABFAB. Check out my trip report (part 2 of Mr. and Mrs. Paris do Key West in January). That was the best 10,000 points I've spent in a while! Would head back there in a heartbeat
