I believe the person you replied to was asking for destinations comparable to Disney in their respective categories. For art lovers like myself, the Cornell Fine Arts Museum (renamed as Rollins Museum) is not considered to be on the same level as the Louvre or the Met. If given a choice of a free trip, the majority would choose to attend the Louvre over the Rollins. As far as I know, the Louvre had also increased their price in recent years. Like it or not, Disney parks are considered Louvres in the theme park category.
The Smithsonian relies on the generosity of the government, donors, volunteers, and others to remain free to the public. If Disney has the same resources, maybe they could be free as well.
Okay, let's use the Louvre as our example!!!
The Louvre is still free for
all visitors on the first Friday of the month after 6 p.m. (except in July and August).
It is also always free for many adults:
anyone under the age of 18
all 18-25 year-old residents of the European Economic Area
Disabled visitors and the person accompanying them
Art teachers
Artists affiliated to the AIAP
ICOM and ICOMOS members
Journalists
Job seekers
People on income support
The price for non-exempt adults was 17 Euros in 2017, and it is now just 22 Euros. The price has only gone up
29% over the past 7 years, and that is ONLY if you buy your ticket at the entrance, and only if you are an adult. It is still possible to get a discounted multi-museum pass.
In 2017 a 1-day WDW ticket cost a max of $124. this year they go as high as $189. that's a
52.5% increase over the same time period. At WDW, children as young as 10 pay the adult price, and children ages 3-9 cost almost the same as an adult: $184. No exemptions for disabled guests. Can you even imagine that?
The poster I quoted made a blanket statement that "major league sports" have gone up as much as WDW, but I debunked that as well. I only looked up two teams, and found adult MLB tickets for just $12. Seniors and children can even still attend some games for free!
It is very much still possible to find worthwhile, inexpensive entertainment values, including world class museums like the Smithsonian and the Louvre. I get tired of wild claims that the price of all entertainment has gone up in price as much as WDW. I've always mixed my WDW visits with less expensive options like FL's state and national parks, going back 50+ years. As much as I like WDW, I also love walking around St. Augustine and collecting shells on Honeymoon Island. Entertainment value is not = to cost.
