We also do the lightweight Cosco seat with a padded carrying backpack that we check. Set it up so the harness height is situated in advance and make sure you know how to safely install it. Depending on your budget and child’s size (under 45 inches and 50 lbs so likely for a 4 year old but it’s expensive to not be able to use a lot) there’s also the WayB Pico which is super light and compact for travel. i would definitely do a stroller for a 4 year old at Disneyland but would rent there through BabyQuip or at the park. I’d also gently encourage you to learn how to install all of your car seats. Kids can accidentally unbuckle them climbing in and you need to understand the install. Most manufacturers usually have videos on YouTube you can look up!
We have the [this](https://wayb.com/products/pico-car-seat?variant=18872782061625&country=US¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gad_campaignid=21869064169&gbraid=0AAAAAC9dO-H75Amz_KnY4bnWzgUbIeHhG&gclid=CjwKCAjw1tLOBhAMEiwAiPkRHhHJG2Pt3p0nYHfpOwAif49_rX369cYHrxNYHvJ0grENsxPt-YNjSxoCOdcQAvD_BwE) one and love it for travel situations like this.
Yup get the trolley or (and) some ratchet straps. If you want to a different seat for travel and are okay with forwarding facing already I HIGHLY recommend the picco
We have a pico and it’s been great. Our kids are small giants. Can confirm the crotch strap is awful and makes it smaller/harder than it should be.
I just did it! My son is 3 and VERY focused on doing everything on his own and like 85% potty trained. it was TOUGH but, it was also a lot of fun. I packed light - no stroller, just the Way-B travel car seat which I carried on my back, a rolling suitcase and the TopoDesign Mountain Utility Tote which has two straps to go on the suitcase handle. I plopped him right on top of the bag and we moved through the airport easy. Having the car seat on the airplane is a game changer. He was strapped in and even if he screamed a bit, he couldn't escape. I had SO many snacks, even things I normally don't give him, and some videos downloaded to my phone. On the way back, since it was earlier, he was struggling because he was hungry. He ripped a bag of puffs in the O'Hare security line, but it was fine because no one was phased and he kept moving. When he did scream on the plane, people were gracious with me.
This is a great option! We have two for my toddlers. I would also recommend a WayB seat, super compact but check the limits cause I think it’s meant for a bigger toddler.
