We did not stay long in Tulum as there were too many tourists for us. It also seemed that the ruins would not be as great as they were in Chitzen Itza and will be in Guatemala. We can give advice on the campings though.
When you get to the beach area, which is quite a walk, there are three campings and a bunch of places with cabañas. An other option is to go a bit towards Punta Allen and in the beginning of the road are a lot of interesting hotels. We spent our nights on the beach campings and in the city.
Note: we were told by our camping that there is no internet or electricity on any of the campings.
– Camping Santa Fe (150MX$ per person, 130MX$ if you stay 3+ days) looked very beautiful. With white sand and very clean.
– Playa Roca (80MX$ per person. nice camping has all that you need.
– Playa Palmas (100MX$ per person) right next to Playa Roca, barely separated and is of similar quality.
Tulum town sleeping
– on our last night in Tulum we wanted internet and electricity so we stayed in “Hotel Hostel Tulum” at the main crossing of the city next to 7Eleven. We had private condo for 300MX$ but others managed to negotiate cheaper.
See our tulum blog post for our experience in the area. We also went to Punta Allen and the Sian Ka’an biosfera
