I booked three nights at the Ontario Marriott (CA) to take the California Bar Exam. After hearing there was tons of noise from the adjacent train tracks, I booked at a hotel down the road instead.

Unfortunately, it was a non-refundable rate. Does anyone have any advice on how I can either get a refund or credit for a future stay?

I know, boneheaded move, but it's almost $700 that I'll lose so I thought it was worth asking!

Thanks!
