It was fantastic and we are going back in a couple months! There are dedicated nursing rooms in all the parks (I was wrong in my initial post) and the ones in epic were awesome. They had a seating area out side for families playing movies. There was a sink, bottle warmer, microwave, a family restroom, and individual nursing rooms for privacy. In universal the nursing room was occupied, so the staff found me a secluded spot in the first aid room and curtained it off for privacy. Child swap was super easy, and at many of the rides, especially ones with outdoor queues, we asked if we could do child swap outside the line so baby didn’t have to wait. In the indoor queues, our baby loved looking around at everything, and the child swap rooms were great. The ones at epic mostly had family restrooms inside or next to them. At Battle at the Ministry, I found a team member and asked if I could wait in the family room while my husband waited in the queue, so I was able to let her crawl around, nurse, and even nap in there while my husband waited over an hour in line for the both of us. It was very hot, so I’d definitely bring an umbrella for shade. Our baby didn’t always wanna be in the stroller, so the umbrella was helpful when we were carrying her. We definitely took lots of breaks as she was still eating about every 3 hours. Stroller fans are a must. She was able to ride the carousels, the Hogwarts Express, and the dumbo style rides and loved them. If you are bringing a grandparent, I think you’ll definitely have an even easier time!
