You still have time to change your mind. ^^
The only concern may be renting a bus or cars to move around there... For this, we need to know the exact number of participants, although renting one extra car may be done on a last-minute ground. So in short, no hurry ;)
Thanks! Will decide soon.
Note also that I am still in the process of waiting for the final clearance for going down there. Staying up is confirmed. Hopefully, Monday or Tuesday I will know.
