I'm looking to book my hotel for OSCon this year. I'm going, of course, but... $185/night at the cheapest, if I'm lucky, at the convention hotel. More likely somewhere around $200-210, not including taxes, fees, and whatnot. (Which likely brings it to around $250 a night) Yeek! While the Perl Foundation grant covers travel to some extent, there's a limit to what I want to burn the cash on. (Not to mention the issue of taxes on the travel portion of the grant, but that's a separate issue)
The Courtyard by Marriot in the Gaslamp district's $127/night base rate, which seems much more reasonable. Still a bit of a haul (about 4 miles) from the convention, but $80/night in savings covers a lot of cab fare.
