Poor signage for stops. No map of pick up points when printing voucher.So could not plan prior to arrival

The poorest of Hop On Hop Off experiences ever. Normally they have been the best. First we could not find the Yellow Kiosk to exchange the voucher to get our tickets.This was the beginning of a nightmare of information and direction. The person in the kiosk told us there was a person on the bus that would exchange the voucher for a ticket. Got on the bus and was told we were on the wrong bus after we had traveled several blocks. The ticket agent told us to get off the bus - we were dropped off in a part of town we knew nothing about or how to get back to the yellow kiosk. Found out later that day there were several different lines for Hop on Hop off and non went where we had intended to visit. Tip: Take the Tram, easier to use and free for those 75 and older. This experience was a waste of time and $$$.

I do a hop on and hop off bus tour in every city I go to, but based on my experience in Prague, since the city is so small and easy to walk around, it was not really necessary unless you do not want to walk much or you have mobility issues. The further away places the bus goes to can be easily gone to with their public transit, which is inexpensive.

Always a good choice. But make sure you know how close the stop is to your hotel and whether you have to exchange the voucher for a ticket. Our instructions said they could not be exchanged on the bus and the tour agency was quite a bit away. We ended up taking a taxi to get to the exchange point and then found out we could indeed have done it on the bus. A bit annoying.

The purple line has only small buses and was completely booked! They did not start in our area until after 11:00am, therefore, we lost valuable hours on our 48 hour tickets. The wait for buses was entirely too long. The purple line, where we were located, only ran until 5:30. So, for six hours we could travel with the hop on/off. Not enough time to sight see at all. I would not recommend at all. Have used this service in all major cities in the world and this is the worst!

Alas,we booked online which required walking a long long way from our central locale hotel to the nearest office to redeem the voucher... can't do it on bus. Once there, which is not close to any routes, first they told us to wait for someone to take us to the red line, then told us after a bit to go walk to the blue line. When we did we got to a line of people so long that we did not get on the first 3 bus and they finally had activated an English only bus. Next we took this past the overcrowded stop that allowed switch to red line to one that was not crowded. That one we were able to take about half it's remaining route when it got to a point where it said that it would not go for another 15 minutes because the driver took his break at that locale. Had they warned us we would have switched routes. This stop was closest to our hotel, so we walked the 3 blocks back to our hotel. Too exhausted to walk back later for anything more from, essentially, our walking tour of Prague. Never got to the castle and its Cathedral.... nor any of the other sites we had hoped to see. Don't buy online if your hotel is not close to Grevin museum. Don't try to join it from the Blue line near Grevin museum. Switch lines before it takes the swing down past Hotel Imperial where he will take his break.

Great way to sight see a new city and to get a lay of the land. Ticket valid for 24 hours.

Prague is a amazing City Friendly People ,good Food ,and plenty of Beautiful Historical Buildings wherever you are in the city.
The Hop on Hop off was a fantastic way to get through the city and enjoy its stunning sights.

Very useful for tourists.

bus broke down and we waited extra time to get back on at prague castle. lost two hours waiting for hamleys to open to get vouchers. Lost two hours of valuable vacation time. Will NEVER book with viator again!!!!!
