I'll be blunt, "you're crazy!"
No you're not, you're actually quiet sharp because you're asking all of us a really important question. I would probably say go for it just for the heck of it. That would be if you were only having one hip, and if you weren't camping (depending on your version of camping). 2 weeks for one hip, as most every one has stated, is still a time when you're on crutches, you're being pretty careful with hip, and with getting up and down, doing 3 sets of floor exercises a day, might be taking pain meds, icing a lot. Getting some good daily crutching is good for you and the docs will want you to be moving, but milling about in the world's largest garage sale might be a bit much. If it were outside your front door and you could go back to the easy chair anytime you wanted, that would be different.
You're doing 2 hips at once. Based on what I've heard about recovery from bilat surgery, you might be having trouble just getting in and out of your chair at that point.
On the other hand, being able to feel like a human again, ya know like garage saleing all day long, is huge for your mental state during recovery. Good luck.
