You first check in on the lower level of The Land Pavilion . The desk is located right beside Soarin'. The tours run between 10:30 am and 4:30 pm and departs every 45 minutes. Make sure to check with Disney for confirmation of times during your vacation. They want you to arrive at least 15 minutes early. This is the second time I have taken this tour and both times I didn't have a reservation. On both occasions, I just walked up to the desk and got on the next tour. No problem at all.
