Arriving next week at the RPR for 4 nights September 10 to 14. Not visiting a park on the 10th as we fly in late. Due to the low crowd levels, should we even attempt Gringotts during early entry on the 11th? Should we arrive for early entry and just explore the rest of Diagon Alley while visiting Gringotts later in the early afternoon to avoid the EE mad rush? What do you think?
