Another plus to 27, if you decide that route, is there are plenty of places to stop for a quick bite, grocery stop or fill up before you get into the Disney prices of places closer to the parks.
Most of 27 is 55-65 mph and pretty open down to 192. It gets a little busy during the week and at commute times, but it usually takes us about 20-25 minutes to get from the turnpike exit to my mom's house (basically at 27 and 192). She's about a 10 min drive to Kidani.
