Yes it was worth it to us. But has most have mentioned, we bought The Key when it was only a couple of dollars more than the internet. We bought it last year when it was around $20 and the internet was $18 per person per night. This year we purchased The Key again when it was $28 per person and the internet was $20. We'll be tendering in Mykonos and Santorini, so the priority tendering is definitely worth the extra amount of money. Plus we enjoyed the embarkation lunch last year - it was very good and a nice, relaxing way to begin the cruise. We didn't get to experience the departure breakfast (because we had to disembark super early), or other amenities on the last cruise, but still felt like we got our money's worth.
