I will be in Amsterdam for 3 days and I have read these amazing reviews about 2 companies who do tours: Those Dam Boat Guys (they offer small group 1.5 hours tour on a small boat and people love it - its personal, funny, informative) and another company That Dam Guide - they also have great reviews, offer a walking city tour (3 hours). They cost about the same and I can`t decide if doing both would be an overkill and if I should just choose 1? Has anyone done both by these specific companies? Are they different? Similar? Cover same topics? They both sound amazing and I just can`t decide. Please help! Thanks everyone!
