[This Cosco seat](https://a.co/d/aYRpGmm) is a seat that is perfectly appropriate for an infant rear facing but ALSO can be forward facing. They’re quite lightweight, perfectly safe, and very reasonable on cost. I suggest getting one of those for the trip.

Not who you asked, but we really like the cosco one. It’s cheap ish so not too pricy as an additional seat, and it’s one of the lightest you the market for carrying through the airport. You can also buy a car seat backpack from 3rd party sellers which was really good for the airport of it all.

We got a Cosco one for traveling. It’s a no frills thing, but it’s light and gets the job done. This looks to be the newer version of what we have: https://coscokids.com/products/onlook-2-in-1-convertible-car-seat-cc331 Also, assuming you know this, but don’t drink the water. Stick with bottled water, especially for the kid if you’re making formula. The resort will tell you the water is fine. It might be in some places in the hotel… it also might not be all that great in for example the ice makers. My wife’s entire company learned this the hard way at a conference at all included hotel thing in Mexico.

I uber all the time with my toddler and we use the Cosco Onlook car seat and use a harness to sit it on our travel stroller. It has worked extremely well and its lightweight and easy to install in cars. My toddler just rides in the tethered car seat when we get out of the uber.

I have the same problem. It doesnt move much side to side but, even with a rolled up towel, the car seat easily tips forward towards the back of the backseat when rear facing

If you fly a lot, the Cosco one is super bulky though lightweight. My kid also didn’t like it as if it made her sore or something. It’s barely padded and just lightweight plastic. The weight limit is kinda low on it too. We invested in the wayb- I know most people will not fly enough to make it worth it but we like it. Can be worn as a backpack which we needed bc we put our kid in the car seat on the plane, too.

You should definitely check if the Nuna Rava is airline approved, there should be a small airplane logo stamped on it if it is. We have traveled literally around the world with the 2 in 1 Costco Onlook. We got it on Amazon and use it in the car regularly for caretakers and it was so easy to travel with. It worked great on the plane and then was easy to fasten into the car. Good luck!

Uh no way am I skipping the carseat. We have the lightweight Cosco one and even when traveling by myself with the I haul it, our luggage and my 3 year old. I usually just rent a car wherever we're going and deal with installing it.

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!
