Encountering a disturbing situation on current Rendezvous on the Seine river cruise. Second night now docked in Paris next to a riverboat restaurant/night club. Loud music literally shaking glass windows/doors blasting into our cabin from 9 p.m. to 2 a.m last night. Now exact same issue for second night. Tauck river boat team says there is nothing they can do about it. They have looked at moving the ship, but say it is not possible. So now 2nd night where we will get less than 4 hours sleep before waking up early for tours. This is not luxury. Poor planning on Tauck's part. Have lost much respect for the company.
