We are booked on the Island Princess 14 day Panama Canal cruise for January 4th. We currently have the Plus Package, but every time I go on the online chat to get questions answered the Princess reps are constantly pushing an upgrade to the Premier Package. For $20 per person per day to upgrade, it doesn't sound like a bad deal. Seems I remember the price difference being significantly more when we booked. Has anyone upgraded? Was it worth it? The additional dining options sound interesting, but being that this is an older/smaller ship are there many additional options available. Thanks.
