My strategy may depend on if I can sign up both my wife AND son (both under my own
MDE account). The "and a guest" wording is concerning still (and an unknown).
But mainly I personally what want to use the preview to experience (in this order)
1) Ride Smuggler's Run with a much lower wait (because I would need to Rider Swap so my wife can go on it while I watch the 2yo)
2) Build a lightsaber or droid (whatever the boy wants) .. and maybe do the other NEXT trip
3) Experience the food (buy a roaster, blue milk, a coke bottle, etc.)
4) Shop the other stores
5) Be able to just wander the land and experience it and check out easter eggs (and the app interactions) with little crowds.
Don't have interest in the Cantina, since I should be going with little kids, but if I end up going sans kids .. that will probably be higher up on the list.
This would let me experience the land with a more relaxed way during a "normal' trip in October -- just hit what was missed last time, get different food and maybe hit the ride again (if lines are short).
