Similar just happened to me today with the "Perks Extra" package on a group cruise that departs in 2 weeks. The Group manager did "something" (Celebrity won't tell me) that was a modification to our booking, and the Perks Extra package was removed as a result. We received an email that we owe $850 by Monday. Group booking customer service told me not to pay it, and that the Group manager is working things out (apparently there were multiple complaints) and that we won't lose our shore excursions paid with onboard credit from the Perks Extra package...but sure does make me nervous when things get messed up and are outside my control/they won't even explain what happened!
