Yes, though it is spelled Capitol, not Capital. I know they are nasty hours, but flying would be ~$200 each!
That is a good point regarding getting a roomette on the way back. Opinions on that? I'm thinking I could do $56 each way for coach and then add the companion coupon, so the roomette on the return trip would only be the accommodation charge of $126, correct?
I'm confused about your plans. If you use the companion coupon, it can be used both ways if you buy a round-trip. Not sure it can be ued with saver fare if that's what you see for price. As to roomette, you can't use the companion ticket, I believe, with a roomette.
