I Personally would not book at the time of the parade, after my last experience. We arrived and were seated at a window table in an empty room, which quickly filled. A lady and her daughter then arrived some 40 mins into my meal and were seated opp us- the Girl wanted a window table and the mother then kicked off demanding one. We were 2 adults and if we were not so far into our meal we would have swapped, but the woman made it clear to us that she thought we were in her table, it made for a rather uncomfortable dining experience considering how close the tables are.
This was my second bad experience at Walts sadly, I want to love the place but really cant, maybe I will Try a 3rd time, though I have to say - the steakhouse in the village was a lot better food quicker service, not rushed, but its not in the park :-(
