Silly me not counting nights correctly.
This is a me problem but I wanted to share. The website said 7 nights and I counted the days instead of the nights. That always confuses me but I think I know now. Count each little calendar box, starting from the first box, that’s the night and then you check out the next DAY at 11am!
Thankfully I booked a changeable flight and the flight difference wasn’t too bad.
