With that said ... Dena, the madam of Sheri's Ranch, wants to show F1 supporters what her establishment's all about ... with a lavish deal that's exclusive to just them.

Besides the obvious ladies ... the $5,200 bundle includes two nights at the brothel's hotel, transportation, steak and lobster dinner, open bar, bottle of champagne -- and even a trophy from the Sheri Ranch gift shop

"With these packages, we offer racing fans the opportunity to escape from the hustle and bustle of Vegas after the race and enjoy Nevada-style pleasure at a luxury erotic resort," Dena said.
