Man that is far from the stadium, and forget taking the bus, that is a 2 hour and change mission. Driving is easier, considering it is probably around 20 miles or so and you are looking at atleast 10 anywhere from the beach (though technically this is about 2 miles from the beach also). It is a great hotel, ideal for cruise departures. I actually get cheap $35 priceline rates at the Hyatt right behind it all the time for my mini getaways . . . ****ty breakfast and pool compared to the Embassy but the rooms come with microwave and fridge and have alot of high tech options.
This question is impossible because we need to know is the wife coming? single? age group? are you a clubber? kids? money? rental car? etc?
Sounds like a lot, but if you aren't a partier, you could find yourself overspending big time getting something on South Beach. Las Olas is less expensive but not as wild as South Beach. Still good times can be had, especially on a Friday Night. Capones 3 for 1 drink specials. Head on east to the beach over at BeachPlace you got Fat Tuesdays and a bunch of little spots.
JCane hit the nail on the head with the Westin in Hallandale, that thing can be a party scene . . . nice azz hotel also, right on the water. I have seen $75 priceline rates on it before and you are real close to the Aventura mall and much more accessible to Public Transportaton to get you to the stadium.
Hard Rock isn't on the beach but it is very central and literally a 10 minute drive to the stadium on the Turnpike. Hell it is 15 minutes from everywhere (except South Beach . . . closer to 25 minutes) and they have a full casino, 6 clubs, restaurants . . . man everything, hell you can head west on Griffin and ride on the airboats and see the Gators if you want
