We loved being able to use the Skyliner to access Hollywood Studios and Epcot. The Skyliner itself was one of our favorite "rides," and it was a convenient and short walk from the main building of the resort. The only frustrating thing about the Skyliner at Riviera is that Riviera is a bonus stop - it's a short ride to Epcot, but depending on the time of day, there may not be many empty cars that leave the main station at Caribbean Beach Resort. Keep in mind that you have to Transfer at CBR in order to go to Hollywood Studios, and there's sometimes a long line there. We walked once to the main Skyliner station at CBR for a morning trip to Hollywood Studios - I'm really not sure if that was faster or slower than starting at the Riviera stop. 

We loved eating at Primo Piatto, but we had to order our food well in advance - depending on timing and covid restrictions, don't expect to just be able to walk up and order (to be fair, we were able to do this when Riviera first opened in December 2019). 

Overall this is a beautiful resort (those mosaics!) and we would stay again, but I would probably prefer being at either Beach Club or Boardwalk to actually have the option to walk to Hollywood Studios and Epcot rather than being beholden to the Skyliner.
