Thanks it was awesome! @maryanneeeee Thats good, yeah same with me I only had 2 days after the tour then had to come home and go straight back to work. You feel so lost, being in London and then next minute being back at work and nothings changed, feels like you didnt even go!
Favourite place would probably have been Greece, sailing and on Mykonos. A few of us guys hired quad bikes for a day and rode all around the island, was really amazing!
With the optional extras, see the post below. Most of the time in the places we would go on a optional extra/ a walking tour/ or something and then have time afterwards to do our own thing, so we would split into small groups and explore. Sometimes its worth doing the optional tours because that is where the bus will be and your ride back to the hostel, but you can always find your own way back. Dont spend to much time worry about it now but most of them are worth doing.
@shikharb Yeah good idea. Bring plenty of underwear tho because at times you can only wash every 2 weeks or so. we had this one guy join the tour and he only had 2 changes of clothes and they were long pants and long sleeve shirts and steel capped boots, it was so funny because the weather was around 35-40 degrees Celsius and he was always drenched in sweat.... so dont be "that guy" on the bus.
I pretty much did all the optional extras. It is impossible for some of them when they are scheduled at the same time... like skydiving and going up jungfrau in switzerland. Your tour leader will announce them on the bus a week or so before you get there and then a couple days before they will get you to sign up and collect money for them. If no one or only a couple of people are keen on an optional extra then the tour leader will cancel it. for example, no one on our tour did the seine river cruise in paris. The only optional extras I didnt do was the Seine river cruise, Skydiving, and the orchestra in Vienna. The tour leader will also throw in some other ones as well that they may organise along the way, like group dinners or winenary tours that arent included and they book a place and you pay separately... if most of the group is going to these then I would recommend you do it as will be worthwhile.
