Mostly the added extras were amazing. Most of the food extras were amazing. I absoluetly loved the Milan experience, as well as special food the whole experience was truly unique, something I will NEVER forget.
I also loved the boat trip on Lake Guarda, it is one of the most beautiful places I've ever been, so worth it.
The Barano trip and the nightclub were the only bad add ons. The experience of boating over and the social atmosphere made the Burano trip fun and worth it, however the food was terrible. The night club was only Contiki people and was generally boring.
On the whole, however, I am SO GLAD I took the "No Regrets" option as all of the other add ons were various degrees of AMAZING.
The trip was very expensive at face value. Considering what we got to do, and the overall experience, it is so unbelievably worth it!!
