Correct @UUNetBill - in the last week alone we've had over 500 different browser versions visit the website, and when you add the different privacy settings at the user level on top of that, well you begin to understand the challenge. With the ever-changing rules for different countries, and even states in the US, unfortunately some times we have to take a whack-a-mole approach when it's an issue that pops-up but is only reported by 2-3 users a day, and even those users can't reproduce the issue when we reach out.
@carolina cruisin one of two reasons are behindi the number of boarding times available. If you are arranging your own transfers, then all the times shown would be all of your options, and the longer you wait after Online Checkin opens at 21 days the fewer choices you would have. If you have your transfers arranged through us with a pre-cruise hotel or flight, then if there is only one choice it is the time that most closely aligns with when that transfer will arrive at the pier.
