I don’t know if there are 2 Deltas, but the one I stayed at is on Dixon Rd (at Hwy 27) and is closer to airport than Sheraton Conference Hotel. It is the old Skyline Hotel (decades ago) and I think it was also a Renaissance for a few years. It’s also a good option as I used to be able to BRG it for around $100/night. Of course, now I can’t BRG much of anything, but the MAR price point is still very good. And it has a nice lounge on the top floor.
