I'm headed down (not to a resort) solo for 15 nights to work on my parent's old home. It'll be lonely but there is plenty to keep me occupied. If I get itchy, need a recharge, or need to see other humans I'll hop over to Disney. May even book a night or two at the last moment just to relax but it is spring break and things looked full. I know I'll be lonely only at the start, I have my family at my side at all times through texting and video conferencing.
I think your trip will keep you occupied. Make a plan, not that you have to stick to it, but it will help guide you. Disney Springs shopping can take up an entire day all on its own, and you know you'll go back for something you saw another day
