Depends on the amenities you like. In 1999, NSXPO was at Embassy Suites.
Most of us stay at one of the motels on Fremont street - we have stayed many times at Best Western De Azna; they offer AAA discount too. Since most likely you will be in a rental I presume, parking is not an issue.
Occasionally we have stayed in Salinas - primarily because we had some coming with large trailers.
Now if you want to splurge a bit, try Carmel; there are a few nice intimate small hotels - like the one Doris Day has.
