Tour did not meet my expectations.
The pace was actually 12 to 15 mph and not 8 -9 mph as advertised, we always seemed to be late; and the only time that could be made up was during the riding. I would not describe the pace as casual. Unless you were a strong rider or had an e-bike, we felt we could not stop for pictures for the fear of getting lost. One rider dropped a bottle at the start of the ride and by the time it was put away, she could not see anyone up the road and did not know which way to go, so she decided to get on the sag wagon. On-going bicycle problems which should have been resolved the first day. Riders kept getting 'lost' due to inadequate group management which caused delays. Some riders kept having problems with their bikes, brakes improperly adjusted, loose handlebars (to store the bikes in the trailer, handlebars are loosened), group start riding despite not everyone being ready. Riders brought much more luggage than is recommended and there was inadequate space on the bus for all the luggage which ended up in aisle. Every seat on the bus was occupied; back row of bus has inadequate viewing and cannot hear instructions, sight descriptions over the speakers. One bus driver had unhealthy health habits, such as directly drinking from the 5 liter jugs used to fill up rider water bottles; he was always the first off and last one on despite record temperatures (one time after everyone got on-board, he went for a smoke with bus off); the other two drivers kept bus comfortable at all times and never got lost using their Garmin. Five nights were in hotels without AC, which is generally not a problem except that we had near record temperatures of 32 deg C on those days. Even though riding miles on the beach is considered 'fun', most of us did not consider it safe having to dodge bathers and children (it was record heat and the beach was very crowded). Your suggested tipping is ridiculous; seasoned Europeans riders within our group recommended a maximum of 20 Euros per person for the entire trip (bus driver was tipped separately). We had 15 riders, two guides would have been helpful to avoid losing riders along the way. I had never been on a multi-day bike tour, but others in the group had been on several and they did not think this tour met expectations.
Now the positives. The bus broke down on the worst possible day but we were able to proceed after a 6 hour delay for a new bus to arrive (this was handled well). The tour guide was very knowledgeable and had lots of information to share.
I will post more details on TripAdvisor
