2 hours BOAT trip on Thames

I propose to organize picnic TRIP on the BOAT with prosecco or wine. Duration is 2 hours. Price for 2 hour boat with capacity MAX 8 people is 140 Pounds or 18 pounds around for 1 person +alcohol (not including in the price of boat’s rent). Boat is located on Riverside Walk, just next to Kingston Bridge. Bring a picnic with you and take a leisurely trip along the Thames in either direction from your starting point.
