22Sept2022: Booked an RS for Celebrity Solstice 5nt 2Jan2023 sailing. MoveUp to PS available 25Oct2022, happy with RS so only made a minimum offer, bidding range $500 – 1,250pp. 31Dec2022, 2days prior to embarkation day – my bid still showed Pending and unable to Modify or Cancel, but with a comment “The time period to modify or cancel your offer has passed.” Clicking on “Don't miss out! Click here to see other upgrade options on your upcoming cruise and to make an offer” jumped to the Welcome to Celebrity MoveUp bidding webpage, with a comment “Not eligible for upgrade.” Received the email from Celebrity that “our offer to upgrade to a Penthouse Suite wasn't accepted.” 1Jan2023, 1day prior to embarkation day – my bid showed Expired. No worries, the RS with The Retreat experience was awesome!
