We visit Vegas 3-4 times a year for 2-4 weeks each time. Our main stays for a lot of years at non-closed casinos have been Boyd casinos (many) & Four Queens. I agree Four Queens offers are better but Boyd is also great! From friends & my play, it seems that $5000-$7000 will giver you free rooms & some freeplay or food credits. With such offers, I've also received extra free buffets from the slot desk (including seafood buffet for 2) & comped nights beyond my offer which I had originally booked at Emerald rate (from a host). After playing at Gold Coast when not staying there, I now receive free room offers. I would feel very comfortable booking week-night rooms at any Boyd casino, particularly at casino rate, & believing that I could either get my nights comped from a host &/or that I would later receive free room offers. If your play is higher, week-end nights might be comped the first time. At $5000 -$7000, we receive offers for any day o0f the week. We even continue to receive offers from Blue Chip where we only stayed once on a drive to our son's in Ottawa.
We've never used a host. On one trip, we arrived a day earlier than expected and Main Street was totally booked. The slot club called a host who phoned around and gave us a comped room at Fremont.
