- You get to see lots and lots of people you might normally not see because they're usually geographically separated -- bigger weekends tend to draw people from lots of different locales.
- There are lots of different choices of what to do at a given time during the day -- if you're too tired to dance, you can go listen to folks jamming down the hall.
- You get opportunities to dance with new partners all the time.
- Frequently, the bigger festivals/weekends encompass other dance and song forms as well -- blues, morris, shape note singing, swing dancing, and Appalachian clogging are examples of other sessions I've seen at bigger weekends.
- It can be difficult to get a dance with a particular partner you don't get to see because "find me" may not be a successful strategy amongst several hundred people on-site. But you do to dance with lots of other people.
Anyone else have something to add to that list? (We'll be talking about smaller weekends on Monday.)
