Wow! BIG changes!!!
Ok first- bummer on all the home stuff and your uncle

how awful, sounds like God is testing you!
Second- birthdays don't go as planned but looks and sounds like lots of fun still! How exciting for the Elsa doll!
And finally!!! Ahhh! You're no longer part of the September crew!

BUT a cruise sounds like the perfect alternative! I had no idea you were planning on a second baby this year! How exciting! A cruise will be perfect (although let's hope no morning sickness while on a cruise!) you can relax! People potty train their kiddos in weekends, so you should be able to do it in time if you set yourself to the task!
Man, so much going on, but I think you made the right decision, so hard to cancel a WDW trip, I'm sure, but must be a huge weight off your shoulders at the same time. They are definitely a financial burden and I can't imagine the stressors with trying to do a short trip at that!
Hopefully you can book the new ship you haven't tried, would be fun to see the differences! I get they have a BBB on the ships too, so maybe you can plan an extra little surprise for Charlotte to make up for the changes!
Hope all the home stuff works out for you SOON! I'll be praying on it!
