Any of y’all go to the Nattie in Miami? Need some hotel pointers

So we’re planning on making a road trip for the game. We’re a bit on a budget and are all down to just skip the actual city of Miami and hang around Hard Rock Stadium for the day before and gameday. Is there enough to do at or near the stadium? Obviously we’d have a car so any cheaper area within a 30 minute drive of the stadium would be great

Thank y’all and Roll Tide
