hotel room idea
Our room is bursting at the seams, otherwise we'd say yes. I just booked a great hotel deal yesterday (april 21). Expedia.com has the Hawthorn Suites Columbus West at $60/ $65 a night. This is almost 10 miles from the convention center but it's about a 12 minute drive. We stayed just as far away last year and drove in each morning. This hotel has 2 queen beds, refrigerator, free breakfast, indoor pool.
At these prices you can maybe find some roommates. Best wishes, looking forward to seeing you at nats.
