Hey there Patrick and welcome to planDisney!
Brunch is a way of life at my house. I started dragging my entire family out of the house for those Sunday morning (or afternoon) meals and now if you say brunch around my goddaughter she lights up like a Christmas tree. Let's get you to
Raglan Road Irish Pub and Restaurant so you can enjoy a hearty meal of
Kiss Before Shrimp and Salmon Royalty to start your day.
It is a very short walk from
Disney's Saratoga Springs Resort & Spa to
Disney Springs. In my experience, It's pretty easy to get through the security checkpoint that early on a Saturday. If you have a 9 AM reservation you should be ok to enter a few minutes before. But in the event that you are delayed and a few minutes late for your reservation, don't sweat it. While I do try to be a little early for my meals, I've never been turned away for a few minutes difference.
Patrick, I hope I've been able to ease your mind. Have an amazing trip. While you're in Disney Springs, be sure to stop by
The Ganachery and get one of the amazing sandwich-sized s'mores they make. I know you'll have just eaten but Disney calories don't count!
Happy planning!
Taylor
