Pat- I'm chuckling to myself because we feel the same way about the traffic and parking issues in Simpson Bay. That's probably why we love to eat in all the great little places in Jordan Village. Parking is easy (we certainly could walk from Rainbow but we're on vacation!) and there's usually a security guard and his dog patrolling the area for the Medical School.
As for Simpson Bay, we usually can find a spot near Vesna's as we go there at least once a week. It's our favorite!! We'll also venture out to Isola because we can get valet parking at the casino. Other than these 2 ,at our age it's just too much of a problem to try to find a parking space.
Enjoy the rest of your trip!!
