Chani--
i did read what douglas explained, and in his situation perhaps it was seamless. for the date and time i was searching, for the granada-seville leg, there was a 2.5 hour 'layover' between the bus and the train. there was an option for us to take the 7:40am bus and only have a 24 minute layover, but we are trying to make this a laid back trip, and getting up at 5am to make a bus does not fit in that plan. so the thing that bothered me was spending 3 hours in transit from cordoba to granada and then 5.5 hours in transit from granada to seville. honestly, i just want this to be an easy trip. last year we did: fly direct to madrid, 4 days madrid, fast train to barcelona, 4 days in barcelona, fly direct home out of barcelona. it was the best trip because we were able to relax and have fun and didn't spend all of our time traveling (i travel for a living so this is important to me). i thought that's what i planned for this trip. just you know...longer. except maybe i didn't.

please excuse me while i quote you and then use all caps because i'm so happy. ahem...
"Once you've chosen your departure, destination, and date of travel on the ALSA website. You can see what services are included in each of the different bus types by clicking on the words; 'Normal' or 'Supra Economy', (below the arrival time), next to the small grey dog and bicycle icons. "
THAT IS THE INFORMATION I NEEDED!!! I SEE IT NOW! THANK YOU THANK YOU! i feel kind of stupid having not been able to find it myself, though i did check the website. and googled A LOT (and got lots of 'yeah busses in spain don't have WCs' and 'there was totally a toilet on our bus' conflicting comments.) so yes. there are toilets. great.* thank you i feel better about the bus now.
so new question--did you book the bus in advance or at the station? thanks!
*it should be noted that many would think i'm being weird about this, but i assure you, i have a very real medical condition that requires me to not be on a bus for three hours without a toilet at least available in the case of emergencies. i had a very rare form of cancer last year, and resulting major surgery that has forever changed how i process food. i often go 40+ hours without eating to avoid this issue, but even then i can get sick having a sip of water. so yeah. i need to be near-ish a toilet i've found ways to still travel and for that i am proud.
Maria--
yes, that was my thought--that we'd just fly directly to granada some day in the future. we love spain, so we will certainly return, and i've seen some good deals out of PHL to granada on american. but it looks like we may be able to keep it for this trip, so yay!
