Leaving the country is a pretty extreme example, since that's such a huge financial upheaval and has many logistics involved. But it will affect habits for some people.
For example, as Disney removed certain perks (Magical Express, EMH, etc) and increased their prices, we've gone from making Disney our big yearly family vacation to making it a once every three years trip. Will an overhaul of DAS and/or the addition of needing to buy G+ make us never go to a Disney park again? I can't say for sure, but it will continue to affect how often we go. Especially as we compare prices and disability accommodations of other vacation options.
