6pm is a great time for us. We're trying to avoid any later because we have four kids under age 5 and would like to keep their bedtime somewhat regular. I'll be checking every week and I have alerts set up.
How exciting! I just customized ours last week.
I'm already having the Home alone, we slept in! reoccurring nightmare.
Our flight leaves the airport at 5:50 AM. So we have to leave the house around 3/3:30 AM to get there a little after 4 AM, go through security and get to our gate. I'm giving us plenty of time because of the wee ones. Thankfully it's only my immediate family flying out (4 adults, 2 kids) and the rest of our group flies in later. I'll be at ease once we're up in the air and I can try to sleep or something.
I'm also making sure my sister brings our hard tickets just in case there are some crazy issues with our magic bands. I also made her take a picture of each card's bar code and number as backup.
