I just chatted with Princess online and they're telling me I can board at 10:30, let's hope that holds true. But I didn't think about B2B cruisers, ugh! I just checked the site and it doesn't look like there are any 7 day or 14 day itineraries that go out a week before us, so maybe that's a good sign? Regardless, we plan to have our running shoes on and will scope out the deck plans so we know our path ahead of time. We know to not use the 1st bank of elevators we come to. Geesh, it's stressful to plan our relaxation, lol!
