Based on my experience, I'd do my best to change your mind.
I stayed at the Nikki Bird (HJ's) years ago, and it was my last time offsite. The "free transportation" is unpredictable. The buses are nothing like Disney's, they are hot, Laidlaw school buses. You could be ready to go to the parks at 9:00 AM, but your bus comes at least an hour later or so. They run on a schedule, not constantly and on top of it all, they are always at least 30-40 minutes late. Likewise, you could be tired at 3:00 PM and wish to return to your room for a break but your bus does not return until 6:00 PM or so. They leave you far from the gates and at pick up time... good luck! You'll have herds struggling to get in.
By the time you get to get in a bus you'll probably have to travel standing up, as they stop at several resorts to pick up more people and chances are thaat your resort will not be the first stop. It was just not worth the aggravation.
