Mine depends on the season. If it is late spring/summer I will go straight to Pompeii because nothing says BGW for me like the drop and the ride music. If it is HOS season, I usually head for Killarney and check out the decor, although I may alter that if the 2020 layout is the same as last year's. For CT I go back to Pompeii and check out the lights. Unfortunately I am a slave to routine.
Usually Killarney, it just feels correct to start out that way, Plus the vibe of that hamlet is my favorite, its a great way to really start my trip. Though if I'm really itching to get on rides I'll go towards Italy first.
I generally head towards Killarney most of the time but it's not a set in stone habit. Last year I actually headed toward San Marco most of the time as I wanted to get pictures of Pantheon's construction progress.
As long as it doesn’t interfere with catching my first show; I almost always head to Nessie first.
Otherwise, Ireland is my favorite place to start. I love seeing the morning dew on the flowers in that area; plus the cooler temps. Also, maybe it’s because I think of eating Lucky Charms at that time of the day, but I dunno.
