I like when we stay onsite , but we own a starwood 2bdrm lockoff villa vacation property on Int'l Drive.
Most of our trips down this decade have involved us using our vacation property, and it has been great. Only 5-7 minutes from the property, and will take a maximum of 15-20 minutes to get back to the villa from any parking lot in WDW.
A big plus for us is the kitchen, and space to spread out. Pretty easy to fix breakfast in the morning before heading out to the park, and can take care of meals at the mid-day break.... or have an early dinner at the villa before heading back out for the evening.
Another plus.... IN ROOM LAUNDRY MACHINE!! You don't have to pack for each day you are there, or pay a huge price for mousekeeping to wash your necessary clothes.
