We are only at 200 days but cruise Princess for the experience rather than the Loyalty benefits. The laundry service has ruined pants that were sent in just for pressing so we don't bother with the "free" laundry anymore. We do like the self laundry so that's a Princess plus. The priority tender service is a nice perk and my wife likes the 10% off in the boutiques. Getting a little back on ship excursions is nice, but we tend to book our own excursions. We have over 100 days on the books coming up and booked for the itineraries. Just like you, Princess provides the experience we enjoy.
