For many years, we focused SO much on rides, but the last few trips, really took some time to look around.
Like this last trip, I sat near Transformers, just taking a break, and watched Megatron meeting and greeting, and it was so fun. I have never even seen a transformers movie, but it was entertaining.
Really enjoyed the Bourne stunt show. All of the live entertainment is super fun. the Blue Brothers, etc.
The HP entertainment is pretty good. the IoA ones though are usually in the sun, standing, so that sometimes is not ideal, but they're not that long. I also agree with just sitting and watching people doing HP spells. I LOVE exploring Knockturn Alley, and enjoying some ice cream from Florians back there, or there's a great little spot next to the Menagerie shop to relax.
Looking at all the shops is a lot of fun, especially if they have props and collectibles.
Seussland is great for pictures, and just taking in the scenery, and I agree that the trolley ride is fun.
I can't do Forbidden Journey anymore, but you can totally just walk the queue and take your time, etc. then tell them at the end that you are not riding.
I've read and heard a lot about ride 'tours', but I don't know if they still offer those, or when, or which rides might still be doing them. I do recall they were totally subject to availability.
There's a few shops to explore in SuperHero Island. I often don't ride Hulk, and do not ride Dr Doom any more. If the characters are out, can meet them, or just watch others meeting. Green Goblen is often hanging around there.
Have fun!!!
