In all fairness, you are not exactly a demographic that Disney is putting any major emphasis on, in terms of college age kids. You said that you traveled to WDW several times this year with friends.
Judging by the timeline of WDW vacations you have displayed, you stayed on WDW property for one trip (April-Pop Century) out of the three tips you mentioned. Each trip was with one or more friends so its safe to say you split the cost of the room on each trip with one or more people. Pop Century in April averages about $175 per night for rack rate (no discount). That would be appx $90 per night if you split it with one other friend. The other two trips, you stayed off site and again, split the cost of room w/ friends. That would put you in a demographic of college age people who stay offsite a majority of their trips and are not dropping any major coin for the one time you decided to stay on site. Not exactly a demographic I think Disney is putting any major emphasis on in terms of advertising dollars and far from college age kids with "unlimited spending accounts" from mom and dad.
And please take no offense to my post. I think it is great you are able to travel to WDW several times a year w/ friends. That is seriously awesome. I am simply discussing the aspect of who(m) Disney may be deciding to allocate advertising dollars to.
