I've booked a ganjatour http://www.ganjatours.net/ for tues 14th at 1pm and it's currently just me. I've asked them to let me know prices if I brought anyone else along. Will post details of these prices as soon as i get them.
This is my 25th (ish!!) trip and although I'd say 'I definitely know what i like', I'm certain that i've fallen into habitual patterns each trip that prevent me from experiencing some of the lesser known gems! After reading Twichaldinho's ganjatour report I'm sure that the folk at ganjatours have knowledge, experience, personality AND interesting stash to contribute to the tour! Looks great to me!
Let me know if you're interested - i'm happy to pay a bit more to get all the attention and i'm equally happy to pay a bit less and share the tour!
