The trip to Puno started at 6:30 a.m. and everything went great. Pick up, border crossing to Bolivia, guide pickup. I had my personal guide from around 11am to 6pm which was very exceptional for me. We looked at the church in the city of Copacabana, had dinner and then took the boat to the island of the sun, where we then walked over for about 1 hour. Then we drove back and he accompanied me to the bus. My personal highlight was that I was able to leave my luggage in the morning beforehand at the bus company with which I went directly to Cusco in the evening and actually got it back in the evening :) And the whole thing was organized by the tour. We were back in Puno around 9:00 p.m. The only drawback is that the tour was very overpriced, as I found out afterwards. If you organize the whole thing yourself, you may pay 1/3 of the price.
