If possible and it's a 9 a.m. park opening, I'd get a before 8:30 a.m. PPO reservation at BOG (you can pre-order as little as you like... drinks? cupcake?) and you usually get to ride Mine Train before the rope drop crowds.
We went busy April/Spring Break Time this year (7/10 on crowd calendars). Had 8 a.m. BOG, ate without rushing - out by 8:40 a.m. - rode Mine Train twice before rope drop crowds hit. Then did Peter Pan with very short wait (15 mins) - onto Big Thunder Mountain / Splash Mountain / Pirates of Carribbean with maybe 5 min waits. Seems like fewer people rope drop Frontierland/Adventureland, so if you head over there by 9:30/10 a.m., waits are usually relatively short - though, I've never gone during the summer. Before we had our first fast pass at 10 a.m., we also did Swiss Family Robinson. Then, we had our first three fast passes from 10 a.m.-1 p.m. (Jungle Cruise, Haunted Mansion and Buzz Lightyear), also rode People Mover- followed by 1:25 p.m. TS lunch at Crystal Palace. Worked out well. Peter Pan was our longest wait of the day (used our 4th and 5th fast passes that evening). Enjoy!
