We are also booked B2B2B, ending on the TA. Charter = UGH. Change to itinerary = probably not a big problem for us. I think dry dock unlikely since the Connie was fully "solsticized" this past April, we sailed on the TA following the dry dock. Hopefully we get some info soon so we can rest easy or make alternate arrangements. Thumbs down to Celebrity for not being up front with this for booked passengers!
