No, you cannot. If you stop at the Oasis and intend to go back the direction you came from, then you will have to either exit at Irene Rd. (Exit 20) and re-enter the highway to go east or exit at Belvidere-Genoa Rd. (Exit 25) and re-enter the highway to go west.
I don't believe so, as the food, restrooms, etc. are connected over the highway and can be accessed from either direction.
