You really should also be able to do 7 Dwarves first if you want to. We usually get in BOG right at 8 (no matter what time your breakfast is - before say about 8:30 at least - they'll let you in as soon as you get there). Done eating by 8:30 at the latest and stake out a spot where they hold you for 7 Dwarves (leaving BOG, where you'd turn left to go to the line there's usually a CM stopping everyone there - by the time it opens the line will go back to about BOG). Assuming 7D opens by 8:45 or so at the latest, you'll have time for at least 1 ride and then to go stake out a spot for PP. If you don't want to ride 7D (or after if you do), head right towards PP. Usually PP doesn't open until the park opens (which lately has gone to more 9 instead of 8:55 after the new welcome show) and they'll either be holding you near the carousel or just forming an outdoor queue at PP. As long as you beat the crowd coming from RD at that point, the most you'll wait is about 5 minutes (and most of that will be people stopping to do some of the fun activities in the new queue area). We did this 2 weeks ago and were on the first train of 7D and then got to PP and it was already open but ahead of the crowd. By the time we rode PP the lines for both rides were huge.
