I just came back to san diego, so I apologize if the info is too little, too late.
Anyway as artist mentioned, the bus station is an easy 10 block walk on the main drag, any local can point you in the right direction.
My ticket from ensenada to san ignacio costed me USD 111, which is a tad pricey, you 'may' be better off going to Tijuana and getting volaris air and fly to cabo directly but check online for pricing before you do as they fluctuate quite a bit.
If you happen to have a student I'd, buses are automatic 50% off, but remember to dress comfy as it is a long ass ride.
Cabo is not that great for mongering, but if you are trying to get a mix of civilian action (nubile college chicks, or just locals) , cabo is a good destination for that.
Have fun.
[QUOTE=Sound7;1363061]Around $120 to Cabo one way and look for promotions if any by various bus services, I recall this from this summer. No promotions at that time or discount in play.[/QUOTE]
