While visiting family, we stayed in the Radisson. First time even though we've seen the place for years. It was a pleasant stay. Clean room and comfortable bed. We booked a corner suite so there was room for our daughter on a pull out and we also brought our dog.
This was over the Independence Day holiday, so few business travellers. A good number of tour buses stopped in as Santa Maria is something of a stopover between Los Angeles and San Francisco. The airport location makes adds an interesting touch, even though its a small regional airport.
