We are looking for a 4th member to join us for our Islandic trip Sept 12 to 18th

We are a group of 3 people travelling to Iceland between 12th (2pm) and 18th (11am) of September. 
We are planning to do the ring road (counter clock wise) and Snaefellness. We were supposed to be 4 but one of the members is unable to join. Everything is booked (car and hotels) and so we are looking for one person to join us ! 
Total for car + accomodation is expected to be around 220€ each + gaz around 50 ;) 
Here is the link of our planned trip https://docs.google.com/…/134TpR7Zs4MfHXwnTFcIlPqyurN…/edit…
