Actually, you can go here and put in your departure and destination and get all the times for the whole day: http://www.kallimousine.com/eng/schedule_en.asp

Looks like there is another bus at 8am. Then more frequently after that. I think if you switch your flight so you're landing at 630am it might make it less stressful for you. Even if you were a few minutes late landing, you prob would still make the 735 bus. And who knows - maybe you'd even get out fast enough to make the 710, thus not having to feel as rushed at your hotel. In theory, your luggage should come out first. If you land on time, your luggage actually does come out first, and you switch flights, I don't see why you couldn't be on the 710 bus.
