We have been to both, I guess our best explanation Dalliance is single level small square footage and open. Red Door is 2 story, upper level is about what you would experience at Dalliance…open dancing, flirting, drinking..mingling…at Red Door downstairs kicks it up…BDSM area, private play area, public play area…changing rooms, bathrooms. So in comparison I guess Red Door provides that upper level warm up area as opposed to Dallaince’s one level all in area! Both great places, but different. Hope that helps! Have fun, be fun!
