1. Either way you're potentially bringing a kid through the airport to an unfamiliar area with limited supplies in suitcases. My family brought me to Korea when I was very young and a terrible kid to deal with and they've never said it was worse than bringing me anywhere else at that age. Given the small sample size I have though I'd genuinely like to know which parts in your experience are harder
2. There is more in the world than east Asia and even just sticking to the US there are huge swaths of national forest and many cities with unique cultures that could be just as fun for a kid and even cheaper to visit than international travel
3. Taiwan was huge too with lots of cool things, arcades, food everywhere, the crayon factory, a city full of pampered cats. If you need a string of theme parks to come up with a days worth of things to keep a kid entertained than something is wrong

And I don't mean to be entirely against theme parks. I've been to Universal, Legoland, Disney world, Cedar Point, among others, as a kid and with kids. My complaint is simply why would you choose to go into debt for somewhere like that when you can have just as vibrant an experience with your kids for cheaper doing something else? It's depressing

I try to take the whole family to South East Asia once a year. It's a lot of work and money but totally worth it. It's a freaken experience and my kids get to spend time with that side of the family.

A little memory that sticks out. One night me and my wife were sitting on a porch in Northern Thailand, almost by the border. Rural doesn't come close to describing it. I noticed that the ambient noise of the insects were so loud that it was about the volume of a bar and me and her were talking loud over it.

Where do you get that in the developed world? I am normally a bit amused if I hear a single cricket at night or see a single firefly. And here I am almost shouting over the sound of insects and watching as the grass moves from all the animals hunting each other.

Give me that again over the sanitized fun of Disney. Disney has an animatronic elephant? That's nice. I and my wife and kids got to play in the water with real ones, and the price was under 5 USD.

The plane ticket was the most expensive part at about $1.2k iirc. If you planned ahead better than me it's not hard to find $1k or even a little cheaper, granted I live in a city with an international airport so ticket prices also tend to be a bit cheaper here. A family of 4 could do $100/night hotels and get places much nicer than what we did and have enough room. Food costs are so low in Taiwan we stopped even tracking it. Maybe if you only want to eat at fancy sit down places in the center of Taipei or something food would start to add up. I'd high end estimate $10/meal/person but realistically it's like half that

So say a family of 4 over a week, that's $4.8k plane tickets, $700 housing, $840 food, total for all big purchase estimates here is $6,340. Cheaper tickets readily knocks $800 off without putting much effort into hunting for deals, another $400 off for food if you aren't being fancy with it every single meal (besides the excitement of street food is probably more fun for a kid than telling them to sit still for an hour while there is so much going on outside)

Because of the disproportionate cost of the plane tickets, if you were to stay longer than a week the cost compared to Disney gets increasingly better. There are also many other international locations that can be cheaper, and thousands of places just in the US filled with unique experiences and culture that can be engaging for kids at an even better price tag

If you can afford Disney go for it. But going into debt over it is like taking a payday loan to hit up a Cheesecake Factory when there's a block full of food trucks with a dozen cuisines just down the road for cheaper
