@Kdawg954 added some great info about tail gaiting and parking at the stadium. I included it below.
The average season ticket holder has a Yellow pass, that is the most common pass to be close to the stadium. When season ticket holders sell tickets, they often include a Yellow pass which is a nice perk. Solid tailgating happens in Yellow. Those lots typically only require you to cross the street to get in to the orange lot area. Orange Lot is where the high visibility tailgating happens. You'll see a lot of the more popular Twitter Dolfans there and its pretty live with music. Those lots get passed down from generation to generation for longtime season ticket holders. Waiting list is years to get one. There is no assigned parking for yellow or orange (although if you are foreign to Orange lot, long timers will tell you if you are posted in a spot of somebody that's a long timer (unlikely because they get their when the gates open usually).
Resale pricing for Yellow this game seems to be running between $100 to $200, and Orange Lot seems to be running $200+.
Dolphins sell offsite parking for $25 in advance. They claim there is no tailgating but trust me, people tailgate there all the time. Its not nearly as nice because its designed to jam pack cars in there and its a good 20 minute walk to get to the front of the stadium.
What I did last year for the Xmas day game was do a Twitter Meetup with a guy selling an orange pass. $100 bucks, no brainer really. But I did have a cheaper Yellow pass I purchased just in case and resold that as soon as I got the orange. Then a group of like 14 of us just met up at my SUV. Some parked offsite, some ubered, we just needed one primary spot in a prime area. There was plenty of room.
So maybe consider that option.
