We've been using MMSL exclusively since they lengthened the runway to 7K. They're still getting used to handling jets and have been doing a good job. Like a previous poster said...strictly day VFR ops...hours are 0700 to 1700 (I think). No need for a handler. Tania ([email protected]) pretty much runs things and will act as your handler. We typically tip her 50 to 100 depending on how smoothly things go. They don't accept American Express. If you pay with a credit card they tack on a nominal tax (1.8% last time I was there...you'll wonder why things don't add up if you don't account for it). Fueling is fairly quick and the airport has a tower. Contact Tania for all the specifics. Also, if you haven't been to MX this year you should talk to the commandante when you get there about buying an annual permit, otherwise they'll charge you a fee every time you enter the country. The annual permit pays for itself pretty fast. You'll also need a U.S. Customs decal (2008) for your aircraft and most importantly, make sure your pax have their passports in hand when entering the U.S.
