I would imagine that most people, when they get to the hub, tend to head towards Tomorrowland (the whole "go right" instinct), so Splash and BTMRR would be the best bet. Personally, when we have a breakfast ADR at BOG before the park opens, we hit 7DMT first-it's basically right beside BOG, and most people probably don't think to head to the attractions on the backside of the castle, instead heading to Tomorrowland, Adventureland, Liberty Square or Frontierland. After 7DMT, we tend to go counter clockwise, hitting LS, FL, AL and then TL.
