Welcome!!
Finnegan's is usually the best spot for several reasons.
1. Drinks.
2. A bigger "holding pen" so it doesn't feel as clustered, and it's close to the marquee names.
3. You can knock out 3-4 soundstage houses at the beginning of the event, sometimes within 30 min, and get a good head start for the rest of the night.
As far as S&S and houses - the Springfield pen is now kind of a question mark since they moved another entrance to MIB. If we base it on year's past, it would be Evil Dead, Scarecrow, and Hive.
Diagon Alley is good for some AC and Potter, but it would just take you to Blumhouse. Once done, your stuck until they "open" up the rest of the event.
Hello Kitty is good if AHS is your must-do, but it gets plenty crowded.
Finnegan's will hit Dead Waters and Fallen, and eventually the other 2 front SS.
