We enjoyed our time in Switzerland, absolutely beautiful.
We were very satisfied with the hotels and the personal tours that you arranged, especially the two guides who were extremely helpful and fun as well!
The alps are extremely beautiful, I would love to stay in the mountains (when the weather is warmer) for a couple of days on our next trip!
Lucerne & Lausanne are beautiful cities, which my parents loved the most. It is less crowded than Geneva, and the beautiful scenery around the city made them feel very relaxed . They enjoyed the lakes and mountains.
We went up to Mt Pilatus as you suggested, it was fun taking the cruise, cogwheel & the cable car. The scenery is slightly different from Jungfrau which makes it very interesting.
Anyway, thank you so much for your recommendation and arrangement as well. I will contact you in future for trips like this.
