We have stayed w/in walking distance, driven and parked at Mickey and Friends and taken ART. I would forever and ever suggest/encourage staying with in walking distance. And if I couldn't, for whatever reason, I would drive and park before I would take ART. I am sure ART works really well for some people - my family hated it.
There are places to stay that offer spaces for bigger groups - check out the map that a PP linked - it will help you figure out where they're located. Some motels/hotels say they are a "block" from DLR, and they probably are, but they are some VERY long blocks. Also, motel/hotel websites often promote themselves as being "right across the street" from DLR. That is often very true, as well - BUT, they might be right across the BACK of DLR and it could take 15 or 20 minutes just to walk to the security tables.
We travel with a bigger group a lot of times - there are 7 in our family and finding a comfortable place to stay that doesn't break the bank can be a challenge. We like HoJo - we usually get adjoining rooms. Our next trip in March we are trying Desert Inn and Suites, which will suit the size of our group. It is right across the crosswalk from DLR. That is a bonus. I have some concerns about the comfort of the beds, but we won't know until we get there.
We take sandwiches and fruit and veggies with us when we go to offset some of the less healthy options at DLR. We plan one main meal in the parks per day and that works really well for us. We feel much better and less sluggish than when we eat all of our meals there. We eat breakfast in our rooms.
We love, love, love off-season and early November is one of our favorite times to go. We add weekend days to see Fantasmic!, fireworks and now WOC since they don't usually play during the week during off-season.
Our favorite amount of time is 5 days. Commando touring stresses out some members of our family and makes them grumpy (cough - DH - cough) so we've found that 5 is our perfect number.
Good luck with your planning and feel free to ask questions - we're a helpful bunch!
