Yeah, I've been looking at all the options with Marriott, I'm a snob too, especially when it's on my own dime . Nothing grabs me. Further south, the Turnberry Isle looks interesting (I'm not too bothered about being on top of Dania). If you want to be disappointed by a Renaissance, try the one at Heathrow, it's dreadful, and nearly always priced lower than the Marriotts nearby.
As a local, I can't give reviews on all of the hotels nearby. I actually stayed at Turnberry last year for a work meeting. The room are a little tired and could use updating, but the facilities are first rate. It has (in my opinion) easily the two nicest gold courses in the area accessible to the public. There's a beach club (via a 5 minute shuttle), lazy river ride, beautiful pools, nice spa, great steakhouse etc. , and you can walk across the street to Aventura Mall (a big mall with movie theaters, Nordstrom, Bloomie's etc). I think the W on Fort Lauderdale beach is probably the only other really upscale hotel that's not too far from the Dania store. There's a brand new St. Regis in Bal Harbour that's probably about 20 minutes or so from Dania, and that's really nice -- I had dinner there a few weeks ago and it was terrific. Otherwise, you're either looking at South Beach or downtown Miami for really nice hotels, or a typical chain hotel near Dania.
There's also a Renaissance in Plantation, which is only about 10 minutes from Dania. They just remodeled it and it looks pretty nice, but you'll be in the middle of nowhere for any other "vacation" things you'd want to do.
