For the character photos you may need to leave the 18-55 on the camera. With really large crowds around characters sometimes the wider focal length is needed....I will definitely be getting the 35 mm 1.8, good to hear y'all liked it for the parks!
Frankly, my Nikon 35mm f/1.8 is one of my favorite lenses to have with me and on the camera. Great in low light conditions and tack sharp, and with the wide aperture gives you plenty of creative options. It was the second lens after my kit lens (18-140mm) I would keep this on the camera and be ready to g owith Nikon 10-24mm Lens, I am still learning this lens and how best to get the best out of the UWA.
I'm only taking two lenses, and I'm taking the Sigma 18-35 f/1.8 and the Nikon 85 f/1.8. I expect to use the 18-35 most of the time.
I had the Nikon 35 f/1.8, and it's a lot smaller, lighter,and cheaper than the Sigma 18-35, but the Sigma is so much more versatile, and it should be wide enough.
The Nikon 85 f/1.8 is my favorite of the Nikon primes, and will be used for photographing parades, our high school marching band, and animals. I'm pretty sure I can use my feet or crop later if I need the 50 mm distance.
Good point. Next lens for OP is Tokina 11-16. (Or the Nikon but I believe it is more money but very nice as well).
FOR UWA the key is to place the subject in the foreground. It will make the subject look large in comparison to the items in back..

The Sigma 17-70 2.8-4 mentioned several times is a great walk around lens for vacation because it's so versatile. IMO, that is the logical upgrade from the kit lens. I got mine used for a great deal. OP, you can really stretch your budget buying used/refurbished lenses - just make sure you go with a reputable place like Adorama or B&H. I have the Tokina 11-16 that was also mentioned several times but haven't found it to be as useful as I thought it would be. It's great for night sky photos and I use it for real estate pics but otherwise it is not a favorite. Going to bring it and the 17-70 on my trip to US and WDW in April, hopefully I'll get some inspiration to use the 11-16.
I've got a Canon and use mostly zooms -
For DW last trip I took all 3 of my zooms a 16-35, 24-70 and a 70-300.
I never took all 3 with me (one or two usually stayed in the room)
The zoom came in handy with the Spirit of Aloha Luau as I got some great shots that way but usually it's my least used lens.
Generally the 16-35 stayed on my camera most of the time as I used it for all landscape, parade videoing and firework videoing shots. I used the 24-70 when I knew I was going to take family portraits (but that's a small percentage of the overall photography I do) or would need the closer range. (Castle shows typically, although I really couldn't zoom in enough from the hub with them but my 70-300 wasn't wide enough to get the entire castle in the shot for the occasional fireworks burst).
