Give Adrian, Victor, or Edgar a call at FBO Los Cabos ( number is in the Accu-Kwik). They are the handlers for Universal, and you can just call them directly to avoid the extra charges. I make it a point to call ahead of time, usually a week or so, and fax down all the pax info you can. Adrian has some good connections with hotels, on our last trip he put us up in the Crown Plaza at an all inclusive rate of $90.00 US, even during spring break! We talked to some other pilots that were staying there, and they were paying around $200 US. Try to get into the Finistera in Cabo if you can, they have the nicest pool of all the hotels we've used. One of the above gentlemen will meet you at your aircraft. We always take no less than $500 cash with us, for tips, taxes, etc. The Commandante gets $40 and a bottle of wine, fuelers $10 and/or some...ahem...magazines, and the handlers usually get $20-30. You will need some cash upon leaving, as there are passenger taxes that must be paid ONLY in cash. We paid around $145 for six pax on our last trip.
Another good reason to call one of these guys ahead of time is to make sure that there will be a parking spot for your jet. We had a GIV go down there and they almost ended up repositioning to LAP.
