I really like what what Courtney suggested. You might also want to consider Morrow Bay or the 5 Cities area (Arroyo Grande, Pismo, etc.). I have family friends who spend their anniversary every year at a fantastic, pet friendly B&B in Morrow Bay each year, but the name of the place is slipping my mind :/
If you have the money, frequent flyer miles, and a pet-sitter, I'd suggest getting some kind of deal on Southwest and checking out a new city for a weekend. Portland or even Vancouver could be potential destinations if you're willing to spend the money for plane tickets?
Also JorgeC, I'm wondering how life is as a gay man in Ontario? Isn't the Inland Empire pretty conservative? I heard that a neo-nazsi was running for mayor/office down there a couple months ago. I'm just curious because I don't think I'll get into UC Santa Cruz or Davis, but I might be offered admittance to UC Riverside and I just want to get a feel for how gay friendly the IE is?
