After lunch, it was back up the path, with stops to watch sea otters in the marina and harbor seals working hard at basking in the sun in the cove next to the old Fisherman's Wharf. We then stopped at a British foods shop on the Alvarado Mall, where we bought some good cheese. Finally it was back to the van, which we'd left parked at the hotel, and we hit the road back to the Bay Area.
It's not a long drive back, but with the sun and the exercise, I found myself having to work hard to stay awake, so I stopped part-way along to get a Coke, and we also had to get some groceries before finally getting home around 7 PM. An early night tonight is indicated, I think.
Overall, this was a really nice weekend. I would recommend the Casa Munras hotel as long as you don't mind the walk (about 2 miles or so to the Aquarium, but it is convenient to Downtown and the Fisherman's Wharf area). It looks like it will be somewhat nicer once the current renovations are complete. The rooms are a little small compared to what I'm used to, but the beds are nice. You can stay at other places for less -- the Travelodge across the street was about $40/night less; OTOH our room included two tickets to the Aquarium -- but the hotel staff here seemed very attentive and I'd stay here again if the opportunity presents itself.
