I got seabands for our cruise last year although historically I don't get sea sick and didn't use them for that I wanted them with me. They work for some symptoms and triggers of my motion sickness but not others from what I've experimented with. They help with the nausea and I figured they would based on how I've used that pressure point myself when I've needed to but not necessarily on vertigo or dizziness. I had to break out the seabands on our Uber ride for this Europe trip we went on as we flew to LaGuardia a day ahead but we flew out of JFK so we booked a hotel room near JFK. A 40 min stop go stop go weave in and out of traffic Uber ride had me about halfway through about to get sick so that pressure point to reduce nausea was really needed (had also gotten a headache and was very flushed I guess you could describe it) and my husband saw that. I was so happy to get out of that car when I did. I had to lie down for a bit afterwards and luckily it was late enough that the hotel room was ready.
I def. wouldn't mind bringing the seabands with us on our next trip and trying it out I mean no harm done whatsoever by keeping them on especially as I'm used to them now (they probably will help on Tron, kinda nervous about trying that out) but I do also know my limit. Spinning rides no matter what are just out (I did try Guardians but was so thankful it malfunctioned halfway through), high drops are very hard for me to do but that also is part fear part how it make my body feel but I can attempt Splash or Ripsaw Falls depending on how I'm feeling, upside down rides are a no. I did try Expedition Everest once but that backwards portion really got to me and for our Europe train trip we tried as hard as we possible could to buy tickets that allowed us to switch seats (so we got ones across from each other instead of side by side) when the direction of travel was unknown (which was most of it). The seabands don't help me with that backwards part I found out but they did help me when we were on a train from Belgium to Luxembourg going through France stopping 16 times, the frequent stopping triggered the motion sickness about halfway through. I tried bonine in 2017 and it made me too tired so I stopped using when I kept falling asleep at the parks

.
I did find that my first time around on FOP in 2017 I had my eyes closed for about 95% of it but was able to do it twice in 2022 with most of the time my eyes being opened. Something I did differently in 2022 that helped me out for noises might have also helped in that respect. I got petite sized foam ear plugs (that aren't perfect due to the shape of my ear and ear canal but help none the less), those were very helpful for the loud (for me that is) portions of rides like 7DMT (in the gem cave part of the incline) or the TNT part of BTMRR, even the Liberty Square Boat for the horn.
About 10 years ago I went into urgent care for a sinus infection (which was common for me to have at least once a year prior to the pandemic) and the nurse said "oh my you have windy and twisty and small ear canals" first time I had been told that but I do believe that likely has a direct effect on how I get affected by motion sickness and how loud noises are painful for me.
I did purchase ginger gum for the cruise last year but didn't end up needing/trying that but that's something others have recommended.
That's great you could do spinning cups and the carousel
ETA: Oh and on EP yeah I think my husband and I found we LOVED having it, it was the first trip we did with it whereas other trips we didn't have it. We did a split stay with Royal Pacific for one night (and what a beautiful resort that is isn't it?) and then 2 nights at Endless Summer, worked perfectly! I could see us doing a split stay again
i laughed when i read about your laguardia-jfk ordeal.
Our daughter (now 39) was about 18 months old at the time...
we didn't know that she suffered from car sickness (and i didn't figure it out until about 4 years later).
anyway, we flew into laguardia and out of JFK...
just before the taxi arrived at JFK, she threw up all over my poor husband....
i'd never seen her do that before....not baby spitting up...massive vomit all over him..
and while of course i had many changes of clothes for her, i didn't have any for him (this was back in 1986 i guess)..
i learned my lesson...from that moment on i had a change of clothes for everyone..
but poor guy - he's 6'7" tall and wears very tall man clothes, so as you can imagine there was nothing in JFK that could fit him...
and it was a very very very long flight to come...
i think i did buy him a tshirt, that barely reached his waist...and he had to fly like that....oh well...
but yes, i know exactly what that ride is like (for us it was in a taxi, not an uber)..
i rode expedition everest once and thought i was going to die...i lied down right near the ride and didn't move for 2 hours LOL...
that was before i thought of using seabands on rides..
but i still wouldn't try EE again..
i was too scared to try tron, so i went in the line with my friend (she and i went to WDW together a year ago)...
she rode and i chickened out at the end...
and i also never ride guardians but i go in the line since it's a fun preshow...
what else don't i ride? rock and roller coaster...i think that's all....tron, EE, rock and roller coaster and guardians....oh and space mountain...and at universal there are a lot of rides i don't ride..
oh and flight of passage, when i rode it without seabands i kept my eyes closed, but with seabands i was able to keep them open most of the time..
