I'm not against staying on-site (we've done both and each has certain perks

), but I just wanted to comment on this statement:
On our last trip we stayed off-site on 192, and everyday we were on property and at our destination in
half the time of what it took when we used the WDW buses on previous on-site trips. I just don't want people to think that it takes any longer to drive, when that is not the case.
That being said, obviously this would not hold true if for MK and Epcot if you are on the monorail line or if you stayed more than a few miles from WDW property, but from what I see on the Dis, most off-site guests try to stay as close to property as possible.
Honestly, once I realized how easy it was to drive back and forth to the parks, the thought of using the buses again does not sound the least bit appealing to me.
In any case, thank you so much to the OP ~ you gave a really informative breakdown of your trip that I think could really help people weighing their options!
