Hi mikek (Mike)
1. All the prices for hotels are per double room. I may be able to get a slightly better price in some of the bigger hotels for single occupancy but the prices are pretty much rock bottom.
2. Tolls, one toll for sure going through the Monte Blanc Tunnel which is 43.50€ one way (2017 price)
If you're going around the Nurburgring that is classed as a toll road too (so insurance wise best to check and see if your company list it as a exclusion - some do, some don't, if not then your covered s:D
There may be some more tolls but I've not finished routing yet, but they will be kept to minimums.
3. Hop on / off wherever and whenever you like. I've designed the run for people to do just that, with the free use of mobile phone (at no more cost than your normal UK plan) in Europe now it will be easy to communicate stops and way-points for people joining and departing.
For you guys I'd think jumping off after the night's stay on the 29th Aug, Hotel Inn Design Moutiers €61.29 (+ 5€ For A Towel And Shower Kit !)
(Through the Mont Blanc Tunnel turn right and just in France) B&B Inc would be best.
Morning of the 30th we are 10 mins away from an Alpine Thermal Spa which I thought we'd visit for a couple of hours. cost (i think) about 15€ for 2 hours 39€ for half a day.
4. Confirming, please confirm as soon as possible for the ferry however we've got until Easter (ish) after then I can possibly squeeze someone in but it gets more difficult,
the rooms can be adjusted up to 14 days beforehand - but no guarantee of availability of more rooms. Currently we have 3 rooms free at each hotel booked to us, room allocation will be done as folk confirm.
Once people are confirmed I'll send out a confirmation PM with all my contact details.
I will be listing more info on excursions and tolls etc in the next few days. s:D
Hope that helps
