Spain Tour Reviews
Honest insights from past guests on our 18-Day Spain tours
This was a perfect way to see everything and now I know what I want to go back and see more of - perfect for a first time traveller. The only thing I would add would be an extra day in Germany
The trip of a lifetime!!!! It was incredible, I made lifelong friends and have the most incredible memories forever - and I couldn’t believe how AMAZING our trip leader Hayley is!!!! (And our incredible bus driver Georgios). This was my first Top Deck and Hayley was such a massive part of making it the most incredible trip for me and my group. She is so fun, knowledgeable and made sure everyone had the trip of a life time. She is so approachable and we could go to her with absolutely anything! Georgios was the best bus driver - making us feel so safe the entire time (sorry but he’s parking skills are incredible, like if there was bus parking in the Olympics he would win lol). Anyway, they’re the best, I had the best time of my life and I’m praying I get to do another trip with them!!!!!! Xxxx
While it was very damn cold it was so much fun with the tour group that we had. Also because we were just infront of the peak time, we were able to visit so many places easily. Honestly it's the best time to go
I think that every stop was well thought out, with the tour offered and the cultural experiences. I mean a few extra days in each city would have been nice but that was not the tour I booked.
It was a good amount of time not too long. Well worth the money spent as everything was fine for you. Makes it so much easier and the tours our leader took us on for her first tour was great.
It was a great tour and our guide Maria Diaz was outstanding!! This tour is actually 2 separate tours which we didn’t know when we booked. This led to some duplication and too much added free time for the Heritage tour group. That is my main complaint regarding the Spanish Heritage tour (aka Highlights of Spain and Nortgern Spain)
