Thanks for the response!
I'm looking for a 4*+ in the "Mission Beach - Ocean Beach - Pacific Beach" area. As far as a reasonable parking fee, after doing some test bidding and research with express deals, I noticed the fees end up rolled into the price, so whatever our reservation ends up being includes that cost, so I'm not as worried about that. 20-30 dollars seemed to be the norm.
Our budget is no more than $200 a night after fees, but obviously we're looking for the best deal.
Thanks
