We've stayed at Riverside several times over the years and had a split stay with there, CSR, and Saratoga Springs in February 2024. Honestly, I'd likely give a slight edge to CSR as we were able to park within a few feet of our room entrance. Also, depending on where your room is at Riverside, it can be a "haul" to the main building (quick service, front desk, shopping, etc.). Keep in mind the rooms at CSR were designed to accommodate convention guests, so the room set up is slightly different than other mod resort rooms--not an issue in our opinions, though. Would I stay in either again? YES. I'd based that decision on availability and cost!
