Two girls traveling to Tulum

Im going to Tulum with a friend in march were both 22-23 and we’re looking for adventure and i guess didnt realize how commercialized Tulum was… (i never heard of Tulum before we wanted to go to Cancun originally and then booked a hostel in Tulum by accident).

Is it really that horribly expensive? Were not really out here trying to go to fancy parties or anything.. just trying to enjoy beach, nature , explore the culture and drink at places with good vibes and reasonable prices. Going to rave sounds fun but i would not want to pay 100+ for entry..

Please recommend us some places!!!
