Planning a Big Match-Day Watch Party

Watching a big Manchester United match with a group of fellow fans is always more exciting than watching alone. I've been thinking about what goes into organizing a good outdoor watch party, especially when a lot of supporters are expected to attend.

Besides having a large screen, good sound, food, and enough seating, what practical things should organizers consider to keep everyone comfortable throughout the event? For a larger gathering at a private venue, would renting a Luxury Restroom Trailer Rental be worth considering, or would standard portable toilets usually be enough?

I'd be interested to hear from anyone who has attended or helped organize a large football viewing party. What made the experience enjoyable, and what details do organizers often overlook?
