Hi Mike,
Another satisfied bilat resurf here. I had them done approx a month apart (Feb and March of 2008). I wrote a "hip story" (in this site, listed under Dr. Ball). Like you, I didn't want to go through extensive rehab (over a couple years), so I wanted to get them both done at the same time.
I saw 2 resurfacing docs, and both suggested scheduling the surgeries approx a month apart. Their rationale was that if you assign an arbitrary risk of 1 to a single resurf, and schedule them a month apart, you would have a total risk of 2. However, if both hips are done in a single surgery, the total risk is something more like 2.5. For e.g., the risk of needing a transfusion is much greater for a single-session bilat than for 2 separate smaller surgeries. That said, my doc said that he's done many true bilats and hasn't had any problems and all of those patients are of course very happy. He still preferred the staged approach if my schedule would allow.
I'm happy with the recovery so far. Just returned from a vacation where I did lots of bicycling, lots of walking (3 miles with no thought of problems), swimming, some tent camping, etc. Range of motion is really the only thing that bothers me - picking things off the ground - but it's getting better. The glutes are still weak, but that is just something to work on, not so much of a bother.
Good luck,
-Dirk
