Not really...
The properties used to have a lot more water sports... more onsite things like tennis... you would do sailiing or fishing.. more activities at fort wilderness.. you might be doing more of the tours.
Sure the resorts have some 'kids activities' of different flavors, the marinas are still there, the beaches are all roped off, sure there is some golf still.. but the entire pacing and way people spend time on property has completely changed. It's a combination of guest habits and product structure from the company.
When was the last time you saw a trip report where people talked about doing water sprite rentals?
Now those 'resort activities' all about fireworks cruises, pool breaks.. and maybe the nighttime movies for the kids.
Vacationing at WDW was radically different during the 70s and 80s for those who stayed onsite. The Disney decade started crowding the schedule.. and the ticketing changes that came along with MYW structure and Disney's continued growth and marketing strategies honed visitors into focusing on the parks by bundling hotel and ticket lengths in packages. Add in the marketing they'd drone into everyone in the room TVs about 'cant miss' (anything) and people would run themselves ragged trying to get to everything on property. Who has got time for an afternoon on the lake when there is stuff you haven't seen yet!!!
The pacing, pricing, marketing and scale of WDW killed the vacation kingdom and turned it into the Theme Park Kingdom.
I honestly don't know why Americans insist on having these 350sq ft hotel rooms at a place like Disney when most just use them to sleep and get changed. Euro Urban sized hotel rooms would work just as well if American stigmas weren't already entrenched about what makes a hotel 'good' or not.
