If it’s in the Sand Lake Road area, personally I would take Apopka Vineland Road down to Disney instead of I-4. It’s a multi-lane road with a median, and it comes down right to the Hotel Plaza Blvd. entrance to Disney property. I-4 can be fast, or very slow, and you never know which until you’re in the middle of it.
The Sand Lake Road area in general is very nice, but I agree with finding out at least the neighborhood or subdivision ahead of time. Sometimes people “stretch” the boundaries a bit, to make their property sound like it’s in a better area than it is. So they could claim it’s in the Sand Lake area when technically it’s not.
