We wanted to "Test Drive" the Princess Discovery prior to our group cruise to Alaska in August. Ship is new. Therefore, everything is in top shape. We felt they had some staffing issue - hopefully, they will be fully staffed prior to our August cruise. Even though there were empty tables, restaurant reservations were almost impossible to get on the Medallion App. We finally managed to beg the Maître D for a seating assignment in the Ketchikan Dining room. Reservations for any Specialty Dining options were totally impossible on the App. Our group thought the understaffing may be the major cause of no reservation availability. The new dining program - making specific time reservations instead of "Early" and "Late" seating may also contribute to the dining room headaches. Staff had to manage constant changing diners throughout the evening. Early and Late are far easier for the staff to manage. As for the Medallion App itself... Nobody we spoke with liked it! It would freeze up frequently requiring a total reboot. The thought is good but the actual application is not up to par. We preferred to get the old fashioned Princess Patter and not bother looking at the app for daily programs. One thing we found great on the app is the tracking of shipmates. Good or Bad, my wife always knew exactly where I was! I have taken 23 Princess cruises on ten different ships. Discovery is classed as the largest Princess ships. I prefer the smaller ships. Star Princess remains my favorite!
