Going to USA: Where to buy LPs in CA and Vegas?

Thanks for all the responses! I'm looking for pop/rock stuff. Promos and first presses only.

HI all, thanks for the response... well actually I do have some free time in all 3 cities... Addresses will be most helpful! Do these shops accept credit cards?

Finally booked the hotels. Hopeteh record stores aren\t too far from the hotels!

1. Westin Bonadventure, 404 S. Figueroa Street, LA
-> Think this is bear to Record Surplus. Who has the full address? Think I can even walk there...

2. The Stratosphere, Las Vegas
-> Any stores near here?

3. Cathedral Hill Hotel, 1101 Van Ness Avenue, Sans Frans
-> Any advice?

Thanks all for your help!
