I find this outrage very strange. These are two different concepts. MSC is not a luxury cruise line while Explora Journeys is trying make its mark in the luxury space. It is like comparing Royal to Silversea. The YC is a great concept and we enjoy it very much. However, the YC is an enclave in a large ship that can have in excess of 5000 passengers. It is great to have you own restaurant and pool but at times it can be confining to some. On a luxury cruise line, there are significantly less passengers and the staff to guest ratio can almost be 1:1.
Before it went under, we sailed a couple times on Crystal. The service and experience surpassed what we received in the YC. The advantage at the end was the whole ship was a yacht club and it was more freeing to us.
