Lisa won't know if she can go or not for maybe another day, partially because her vehicles are trapped on account of the idiots tearing down the old building are leaving a rubble that includes a lot of old nails across the access road in front of her vehicles. As they're being paid in whatever useful lumber they can salvage from the building, they don't really care if they leave a big mess behind. And they have an aggressive dog that they let run loose, which is why Lisa can't come out of the house when they're "working."
Afterthought, 14:30: Although the room rates at the San Mateo Marriott are higher than I would like (except for Saturday), I calculated that if I book a room there this weekend, along with some bonus Marriott points that would be triggered for the BayCon stay (stay twice during the period ending May 31 and get 2500 bonus ponints for the second stay), I would then have enough points to get two nights in Tokyo at the Courtyard Ginza. As we're planning three nights in Tokyo, I'd then have to buy the third night (JPY25,000) and hope it wouldn't require checking in and back out again in order to get three contiguous nights. (One thing we don't want to be doing is checking in and out of hotels every day of our stay; it wastes a whole lot of time in travel overhead.)
