I think you can, just have to plan ahead. At two weeks, you should be able to motor around on crutches, so you just have to plan to ice as you travel. I put my handy dandy super duper flat ice pack under my leg for the trips that I took, that helped.
Make sure you tell whoever is hosting that you need a place to sit and if you have any ultra friendly huge dogs (malamutes, newfoundlands, etc.) that they be restrained and conduct themselves with decorum.
I'd take a tylenol before, and take the bottle in case you need it. I would think you'd be fine. At one week after my second, I went to my daughter's pre-party at my ex-house and stood / sat for about an hour or so. About two weeks after my first, I was tooling around with my sister's family on one crutch at the Harvard Coop and a good Mexican restaurant for about three hours.
Both times were exhausting, but that was pretty much it. No drama and I had fun. I think you'll be fine, use your condition to get out of doing the dishes.
Leave whenever you please, or take a nap if you're lagging. an hour down does wonders.
