Beautiful tour - so glad this is the one we chose! The scenery is absolutely beautiful, so even though it's a long day it's well worthwhile. Weather in Scotland can be unpredictable (e.g. sun then hail), so make sure to plan accordingly. Also, since you stop at several gift shops and tourist attractions, you may want to bring an extra bag or enough room to pack away your purchases. The road can be a little windy, so if you're the least bit car sick, it's probably not for you. Our tour bus actually broke down along the way (first time that's happened to us despite a lot of tours), but our AWESOME tour guide, Paul, did everything in his power to make sure that we were taken care of - a wonderful experience despite the hiccup.

Fun times! Gave us chills; a very fun evening for people with good imaginations.

This was a great tour, but I don't think it was worth the full price. We probably could have managed the trip on our own since it was an easy drive and navigation through the park. That said, we did ride in style on the Tour Trekker and our guide was both friendly and knowledgeable.

Great trip, but be careful trying to get in and out of the Basilica if you go on Sunday. We were nearly knocked over by tourists. Otherwise, it's breathtaking and I highly recommend that you go to see it!

We ended up having a private tour since the other scheduled couple did not attend. It was an absolutely beautiful tour through the Spanish countryside and coast. I would do it again and have already recommended it to others.

An absolute must-see! One of the coolest things we've ever booked through Viator. If you do nothing else in Barcelona, do this! The food was terrific and the dancing was phenomonal!

Fascinating experience! It was really interesting to learn about the licensing and laws surrounding the day-to-day life of a sex worker.

Great experience! Our tour guide was very helpful at explaining some of the details behind each stop. I wasn't overly impressed with the Delft stop, but we enjoyed the flower auction and Rotterdam. You may want to eat somewhere faster than the recommended spot, though, so you can see more things.

Having done hop-on, hop-off tours in many other cities, we had pretty high expectations. This one failed to meet them. The buses only ran for a short while every day - and only every half an hour. If you want to stop and take pictures for a few minutes, you'd have to wait a while for the next bus. I would probably recommend taking the city tour instead.

Ghent and Bruges are beautiful. Our tour guide was a little dry, but he gave us some interesting information. Time in both places to walk around and take pictures. Definitely walk over St. Michael's bridge while you're in Ghent for picturesque views.

Very hot, but a great trip. They even provided umbrellas in the case of rain. The guide was extremely knowledgeable and the information provided was fascinating. It's hard to avoid all of the street vendors at Chichen Itza, though.

Beautiful and fun day trip. I have already recommended this trip to several friends and family members. Great show at the end of the day, too.

This is a great an inexpensive way to see the city. We just wish that it ran later in the evenings so that we could see the sights at night, too.

Fantastic tour with amazing and personable tour guides. I just wish we could have gotten off the bus to see some of the sites.

Definitely not enough time to fit everything in that we wanted to say - I recommend skipping the river cruise and staying on the bus to hit all the highlights. I'm not sure that we needed to have the guided tour, but given that we didn't speak French, it seemed to help.

We loved our guide, Mark. He was funny, knowledgeable and personable. The only hiccup we had was getting from the hotel to the bus station and back (you're on your own getting back). Otherwise, loved the trip and the experience!
