Sonny has told me before about his getting calls offering upgrades and I figured it'd never happen to me. And it was funny that she said 'would you be interested in doing this?' which I guess is just standard procedure. She did say it meant we'd have to pay the suite gratuities, which for the three of us is just another $6.75 per day. We usually give more anyway so that was not a problem.
We booked a junior suite, so I guess there was a ripple effect going on this afternoon with many happy people being moved to a truly larger cabin.
