Tulum is fine but I would not ever go again if my friend didn't live there. It's just the intersection of nacros, tourism, cancun spillover, hella overpriced beach clubs. Probably my least favorite place I've been in Mexico, tbh.
I think it’s the hippie aesthetic some of the younger people there have at total odds with its reality that amuses me. Truly more interested in the other parts of the Yucatán though - looks gorgeous.
Bacalar was ... stunning, and chill. Still full of tourists and expats and retirees, but infinitely better vibes than Tulum. Even PDC is more touristy and somehow less... Tulum... than Tulum.
