Everything was great, except for the documentation and organisation around that. Three changes you should make, and I will share this with Carla and Thomas as well:
1. Please provide an English map and booklet. In fact, when booking the tour, you can ask preferences for languages, and ensure that its followed through by the appropriate documentation.
2. When booking the tour, check if this is a first tour and/or use of the e-bikes, and if it is, offer the option of someone spending an hour to rope the persons in... there can be a small charge for it..
3. Share information on online maps, aside of Google Maps. I downloaded on the 3rd day an application that was very helpful, and which made it easier for me to figure things out.
