What People Are Saying About Costello Tours...
and check out some tour videos
"Kathleen is intimately familiar with all of the cities we visited, fluent in Spanish and local customs, and a really nice person on top of it all. She set up a schedule that optimized our time without feeling rushed, with enough flexibility to see other attractions, or just relax if we desired. The hotels were beautiful, the food recommendations were extraordinary, and the itinerary was varied and fun. All of the details were covered allowing us to focus on the experience itself. I highly recommend Costello Tours!
-Steve P. (Spain Summer Tour)
"This tour to Spain was the most memorable vacation I have taken to date. The variety of sightseeing and experiencing the local culture was perfectly paired. The Sagrada Familia in Barcelona and the Arab baths experience in Granada were personal highlights! Kathleen does a beautiful job of explaining the history and significance of the cities while providing excellent food suggestions. I would recommend this to any college student or high school student traveling with a family member!"

Sicily Summer 2026 Tour Reviews:
"The tour was amazing! It was very well planned out and was a great mix between exploring and learning, and shopping and relaxing. Just a few of my favorite activities were hiking Mt. Etna, shopping in Taormina, the boat excursion, the cooking demonstration, and lounging on the beach. Our local guides were great, so knowledgeable and friendly! It was an incredible experience from start to finish! "
-Rob S.
Kathleen is so amazing! Made me want to travel with tour groups only from now on. So organized, helpful and patient in answering anyone’s questions at any time. She took the guesswork out of self planning. Very enjoyable and relaxing trip because of her legwork beforehand. Exactly what I needed and I am planning my next and future trips with her.

"Just took Costello Tours tour of Sicily and it was GREAT! Kathleen made great use of our time and combined historical/cultural events with super fun excursions that I never would have found on my own. What we received for the price we paid was a major steal. Will definitely book another tour - highly recommend!
"Kathleen did an excellent job of guiding the tour - having knowledge of all the stops as well as speaking the native language. She also did a good job of customizing the tour as we had a group of 10, and some people like to be shown everything while others like to explore on their own at their own pace. "
-Sonia A. (Spain Holy Week Tour)

"I loved the fact that although this was a tour vacation, it gave us the opportunity to explore on our own as we wished. Not having the constraints of a more structured tour made the trip so much more enjoyable."
