Whatever.
Try flying a family of four from Europe first. Many of my friends can. not. afford. It. On top of flights.
Anyway thankfully the FP+ debacle is looking like a memory now.
There will be new debacles. Off-site guests are effectively losing the ability to rope-drop.
But yes... let's talk about "on top of flights" -- A family of 4 coming from Europe is going to pay a minimum of $3000-$5000 just on airline tickets.
A week at WDW,, tickets a minimum of about $2000.
Basically, a family coming from Europe is paying a minimum of $5,000 to $7,000 just for airfare and tickets, likely more.
Value resort room is $150 to $200... so often less with discounts. But about $1,000 to $1,400 for the week.
Off-site... maybe pay as little at $80 per night. Oh, but then you have to rent a car and pay for parking, or pay for Ubers every day. So off-site, it really a minimum of $100-$150 per night. So $700 to $1000 minimum off-site.
So onsite for a family from Europe for a week: $6,000 to $8,400 minimum.
Off-site, for a family from Europe, for a week, minimum -- $5,700 to $8,000 minimum.
That's without even considering food and incidentals.
But really... for a family already spending $5,000 to $7,000 minimum,.... the difference between a value on-site (with daily transportation included) compared to off-site (with extra fees for transportation)... the difference comes out to $300 to $400 total, or about a 5% difference in price.
Somehow, I think the family spending $8000 to stay off-site, could somehow change their choices and find another $300-$400 to stay on-site.
