Arrived at SFO at approx 2pm local time after flight on BA287 from LHR. Karen was met by wheelchair assistance so we were pushed to front of immigration line. We picked up our rental car (Jeep Cherokee) from Budget at SFO Airport (long ride on monorail from terminal to rental desk) and drove to hotel - Marriott San Francisco Airport Waterfront. Big and busy hotel but checked in to room 7039. Room was recently upgraded with sliding glass bathroom door. Check-in clerk offered complimentary buffet breakfast.
