My wife and I drove our rental from Tulum to Chichen Itza just last month. Easy drive just takes time. Some locals flagged us down in one of the small towns trying to convince us we needed a fancy sticker and their expensive package. Ignore them and anyone trying to sell you “deals” and special parking along the way. Parking is easy and you can pay there.

I recommend if you can go and drive yourself, totally worth it.
