I booked a cruise last year (3/22). This is a partial view of my invoice/booking from Princess. I booked it direct and then transferred it to my TA for a discount.
Note the wording about the included beverage, WiFi, and crew appreciation. This was before the creation of the term of “Plus package”.
it was built into the price and is not listed as a separate item on the invoice, but as I recall the base price was $40 more per person.
I suggest you review your original first booking invoice and make sure it says the same thing. If it does not, I suspect you did not book it with those benefits. If stated, then perhaps Princess screwed up when they cancelled you original cruise and changed you booking number and cruise. (Assuming it was suppose to be the same deal)
This should help you prove your case! Good luck.
