We picked up fast passes for the newly re-opened Space Mountain right after getting our 50th merchandise but they weren't good until 6 p.m. We had not ever been on it since they remodeled it so since we weren't sure how busy the park would be we didn't want to leave for the risk of not being able to get back in due to the park being at maximum capacity.
Now we had been waiting in the line since the night before at midnight. My wife and I were completely exhausted. So we hopped on the DL railroad and just rode it around the park like 7 or 8 times and got a quick power nap so we could make it till 6 when the fast passes could be used. What a long day, but Wow it was a great memory. If I had it to do it all over again, I wouldn't change a thing.
