Yup...there is a hill from Welfare Rd and a hill to the upper B's at SBR but we are in our early 70's and did the walk MANY, MANY times in January. If at Flamingo or 3 of the 5 SBR buildings one hill is eliminated (or shuttle use). If the OP has mobility issues then that changes things a bit but there are a decent number of places to eat right in the SBR area and save to Welfare Rd walk for another day...
