Tough to say...Davenport is a fairly large town...parts of it are VERY close to Disney, and parts are quite far away...
At best, Davenport is about a twenty minute ride to Disney, much of it along US 192, which is undergoing a major construction project, and is also home to many traffic jams.....
If you have kids, especially younger ones, you may want to give some serious consideration to passing on this one...Consider that you may want to get the kids out of the parks for a few hours one or two days...Now, imagine the minimum twenty minute drive, throw in possible crying and tantrums, and the potential for heavy traffic to add to the stress...
Vacation homes in Kissimmee are generally much better located near Disney Property...Davenport is a lovely community, but a bit far afield if you have young children.
Much of this can be disregarded if you have older kids, or no kids...The traffic problem on US 192 remains, but at least you don't have to deal with an exhausted five year old at the same time, and the extra distance from Disney does make it seem a little more private, and a little more relaxed when you get back.
By the way, it may also surprise you to know that I know EXACTLY where Montague is...Used to drive through it all the time when I was in college...Liked it too, until I broke down there one night, when it was thirty degrees below zero...
