Wow! I'd be bummed, too! I'm glad the A/C can get fixed or replaced. I guess two weeks is better than none (my DW is on a contract and doesn't get paid time off), but I know you're disappointed. You'll make the trip west at some point, and the UP sounds beautiful right now. Can I come?
I grew up on the west coast and have camped in every state but Hawaii. The trip is well worth it - you'll get there. Maybe next year?
FWIW, most companies won't pay for vacation or holidays if you call in sick on the day before or day after and could terminate your employment. I wouldn't risk it.
