My initial thoughts –
Both plans are packed. This generic plan from TP is their “Ultimate Challenge” plan. That’s why they want to congratulate you for actually being able to complete it by putting them in the TP “Hall of Fame”. Both are going to be a very long / hard day for 10 people. You’ll be on a constant march.
You are “late” to all your meal / snack breaks. You slotted lunch at 11:00am, but arrive at 11:40am. You arrive at your 3:40pm Tusker reservations at 3:55pm. You last snack break is a bit behind too
Starting at EE and walking to FoP is such a long walk! There’s no direct way to get there and may be cumbersome for a group of 10
Your Steps #6, #7, #8 –These steps require you bouncing around with excessive walking. I know Jungle trek is off by itself. Also, I don’t know where you are coming from and if you have BBQ at home, but Flame Tree is mediocre and IMHO not worth that trek. (I’m biased though as I come from Memphis, TN – and we have good BBQ everywhere.)
You’ve only given yourself 3 minutes to play at Fossil Games. Even one of these carnival games will take longer to play and you have to go to a kiosk to buy a game card – even more time.
My overall opinion of Plan A = A lot of extra walking and you need to figure out a way to get to your break / meal times “on time”.
Can you move Navi to later? (final step) You still have an hour after your last step until closing. While it would be a bit of a walk, Pandora at night is beautiful. They are actually finishing up repainting the pathways with luminescent paint this week. Plus, this would probably save you 30+ minutes of queue time.
This plan has no free time at all. You really need to put a 10 minute break in your plan every 1.5 – 2 hours. I’ve had more than one person tell me, “I’m on vacation. I don’t need to schedule when I pee.”
These breaks are a buffer for unexpected Magic / toilet / gift shops / drinks / etc.…
It’s always IMHO better to have the break & not need it than get behind.
Fossil Games has the same issue in this plan
For EE, if not everyone wants to do a repeat ride(s) consider doing Single Rider. As a parent, too, I understand the hesitation to not sit next to your kids. However, neither my daughter / wife / myself have never had a problem with other guests. If it’s just a couple of you getting all you’ll all be put on the same train often is seats in front / back of each other. You can get on the ride in 5 minutes or even walk on using Single Rider.
Overall, I like Plan B better. You may need to decide if what may need to be cut to give yourself more free time, but I’d recommend cuts to both plans to make them more realistic.
