There are no set check-in/check-out hours. Reservations are made online and check-in is also done electronically. Loves sends an email confirmation and another email on the day of arrival. You click on "we're here" or something like that, and it activates the site reserved. Loves Travel Centers are open 24 hours so if there is a problem, you can always go inside to request help. I hope that this helps :-)...
