My wife, two daughters and I just returned from the Grand Princess sailing to E Carib. It will now stay on the W Carib run.
Security procedures did not adversely affect flights or connections.
For people planning return flights we left the ship at 0845, although this process usually begins at 8:00 am - we had several people that were very late showing up at US Immigration, hence the delay.
We had a good time and will be posting a long review shortly.
