Thames Party Boats are the best party cruise for adults. I have now celebrated 2 family members birthdays on the viscount, both very different but amazing. The staff really do look after their guests I can tell you that. The best party cruise for adults but also for children they enjoyed seeing the water and the landmarks they were learning about at school. I would highly recommend this company to anyone wanting to create a special, rememberable event as there have been many I will not forget.
