If you ever find yourself in San Francisco, I recommend staying at the Marines Memorial Association hotel there, or as I referred to it, the Veterans Consulate. It is located in the high rent district, downtown, and about as close to everything as you can get. You'll want to buy a membership in the Association first, $35 for active military, $150 for Veterans. You'll save that much on a 2 day stay. They give deep discounts to members, making it, by far the most cost efficient place to stay there.
And if you have a little flexibility in your scheduling, take a look at theirs. In May, General Allen and Major General HR McMasters are both speaking at the hotel, along with several other events which are perks for guests and members. Well known authors are often found speaking at the Hotel.
And the picture is from the hotel library. That's not even half of the books, organized by military subject, and by war. It's the kind of library, I'd love to have in my area.
I do have to caution you though, if you stay at the MMA hotel, you may not want to venture out of it, into the cold concrete jungle of San Francisco and do whatever it was that forced you to go there in the first place. They have a great restaurant, a bar packed with Veterans, and great rooms in the part of town everyone wants to be in.
As a sidenote, they have 20 annual scholarships, and the deadline for applying is 30 April.
If you do find yourself going to San Francisco, be sure to browse the website to see the rest of the facilities of the hotel. And if you go, browse the halls of the various floors, as each is decorated with an enjoyable theme.
