Wow, nice. Too bad I was down there earlier this month! The only "discount" this wonderful hotel usually offers is mid-week, and it's way above 50% off. Business must be slow.
Omni to letiole: Sniff! I didn't see any monarchs, I was too early. There is, however, a really nice exhibit at the Pacific Grove Museum of Natural History at Forest and Central Ave. Plus some great exhibits on native plants, animals, people and geography.
