Want to go dancing?
The Global Tango Marathon Directory lists all the events where you can get together with tango dancers you don’t know yet, and dance all day and night (with breaks for great food).
You can search by date and plan your travel around some amazing weekends.
It includes festivals, but also the much more affordable wall-to-wall dance weekends. Some provide dormitory housing.
Note that many of the events are limited in size and are role-balanced, so be sure to register promptly if you want to go.
