Viator advertised an all day ebike tour. However, when we arrived at Unlimited Biking at 10am to pick up the bikes, Viator had reserved the bikes beginning at 2pm. The bike shop changed our reservation to manual bikes and 1 ebike. This was highly problematic since 2 of our riders recently had surgery. The bike employee assured us that the credit would be processed by the time we returned the bikes. Two bikes broke along the way. While repairing the chain on one, grease ruined my friends shirt. Of course no credit was issued upon our return. This process is said to take weeks to resolve because the bike shop won't issue a credit. It has to go through Viator.
