Proximity to the parks, plus the convenience of not having to drive, and getting dropped off near the park entrance.
See those things didn't matter to us. We actually prefer to drive on vacation...no seriously we do. Having just got back from Jamaica it was a pain, a real pain, relying and paying for transportation and while I know DME is not an additional cost and Disney transportation is not an additional cost there's issues with those in regards to time spent waiting.
It annoyed us that we couldn't just get in a rental car and go while in Jamaica. Would have loved to just explore like we did in Hawaii taking a drive around the island though Jamaica lacks signage overall as well as many other things.
What I will say is with offsite those "free" shuttles aren't necessarily convenient.
That's the things I likely won't really do or want to do in the future. I'd rather drive myself on my timetable. Our 2011 trip was offsite with free shuttles and we ended up driving several days anyways.
We normally always stay on property.
Ahh that likely impacts your viewpoint.
What a hassle to drive to the parks,
It's really not a hassle at all to us at least but that's purely personal preference.. The only place it became an issue was with MK when they changed the traffic pattern overnight and the way we went the day before was not the way we went the next day. Oh and the other time their sign directing to parking got knocked over and we missed it the first time
Well see now with the parking fee for onsite stay it factors into things. It would add up for sure to pay at WDW but that just becomes factored in.
get directed to park in a specific spot even though there are much better/closer spots available
That doesn't bother us really. We encounter it many other places on vacation and everyday life.
then tram/walk in the heat to the park entrance.
You'd be waiting outside in the heat for your transportation like a bus to get to the parks and honestly the wait for the trams on average is probably less than the wait you'd experience waiting for a bus or boats. Even during the lowest of crowds during Irma nearly every single time they had a tram ready and waiting for the cars that were parking and getting out. We loved hopping in the car crank the AC on and go and be able to do that at the end of the night too. The parking trams getting to the parks and from the parks were pretty darn efficient in our personal experience.
We missed just hopping on Disney Transportation from/back to our resort badly the entire time.
I will admit going back to the resort isn't as easy when you're far enough away. Us? With our traveling style presently we didn't take mid-day breaks. I had built that in when the in-laws were going but after they backed out for stamina that was out.
Combine that with lousy FP+ availability at 30 days
Since I don't have any experience with FP at 30days I can't comment so much on that. That's why it made my number 1 ranking for onsite; whereas for you it was #4 behind Disney Transportation / Convenience, Magical Express and 180+10 for ADRs
no DME when getting off plane so having to retrieve luggage and then get rental car
Not a big issue at all for us. We do it everywhere else and it's not a big deal. I will say I do like
Avis Preferred when we book with Avis so you can most of the time skip the counter and go onto your rental car.
we basically came to the conclusion of "Never again" when it comes to staying off-site.
Hey at least you know.
All in all we value different things which is completely fine. Didn't want this to become a big tangent just thought it was interesting your list in comparison to my list. With 3 things to entice me to stay onsite versus exploring the nearly endless hotels out in the Orlando area and Universal's hotels getting rid of 1 of them can really impact our decision for us.
