We got an ADO bus from Playa to Tulum and decided to stay there the entire day. The bus ride was 50 minutes and we paid 100 MXN. Arriving in Tulum, we took a 5 min taxi ride to the Ruins of Tulum. We walked around the area, had lunch on the beach and ended the day with a boat ride and snorkeling.
It was a fun day, but there was a lot of seaweed (sargassum) in Tulum as well. I didn’t feel like I could get disappointed, it’s only nature, it might even be caused by us humans, just be aware that the beaches might not be as stunning as you’d imagine. I still recommend visiting Tulum, especially the ruins but a tip would be to visit some cenotes instead of the beaches.
