I'm here now 7/22 @7:25 and exhausted back in my room at the HRH. We started this morning by waiting at the gate 7am. They let us in the main gate sometime around 7:40 and we walked straight back and into the Harry Potter area. While waiting at the main gate we saw them escort a large group (100) into the park about 7:15. I asked and was told this group was with Virgin tours and had special privileges because they were a captive audience (I don't know what that means). They also brought a horticulture tour group through around 7:30. Tip about entering-when walking in from the Seuss side make sure you take the left hand shortcut behind the carousel. This will get you their much quicker. We rode FJ twice (yea, I barely fit but they pushed hard and let me go, I didn't see anyone turned away.) After this the line for Olivander's was already very long. Too long for me to wait. I hung around and people watched while the rest of the family rode DC a couple of times. Enjoyed a frozen Butterbeer. It tastes like frozen butterscotch and was very good. Buy this in Hogshead Tavern with no line instead of from the outside stand. The shopping was very crowded and the store clerk told me they had sold out of a lot of things. The best bet is the candy store because it is easier to restock food items. It looked like they let the non hotel guests in at 8:45. The first sign of this was the appearance of one of the dreaded South American tour groups. We left the area soon after and spent the rest of the day in other park areas. I didn't notice anyone selling the express tickets but I saw lots of people using them so they must have been for sale.
Great info thanks!
