Just 4 weeks until we're in the World!!! As I continue the never-ending work of perfecting our FP+ selections and general plan, I'm wondering what the wisdom is about the best time to start using FP+ after arriving for RD at MK. Of course, our priority is to ride Stitch's Great Escape as many times as humanly possible, so we'd really like help with that. 
Just kidding folks! So, we'll be at MK on a Recommended day, with TouringPlans predicting a crowd level of 5. It's just my husband and I, so no concerns about wrangling children and the like. As of right now, the plan is to arrive for RD and head straight for Adventureland to do POTC and Jungle Cruise. Our FP+ window for BTMRR opens at 10am. Is that too early? Is it possible we could get onto the ride with a minimal wait by just heading straight there at RD instead? If so, it'd be great to avoid burning a FP+ on it. Still, we'd rather not have long waits at POTC and Jungle Cruise either, and I've read those wait times can get pretty bad.
So I guess my main question is, at what point do lines get long enough that it's worth starting to use FP+? Is it 10am or closer to 11am? It's be great to maximize touring with short stand-by waits for as long as possible before starting to use FP+, especially since I'm concerned by the time we reach Fantasyland (which has a few things I'd like to ride for nostalgia's sake, at least) lines there will be too out of control for us to get anything done.
FYI, we plan on touring generally in a clockwise direction, so we're not looking to do any commando-style park criss-crossing.
What do you all think?
