Now, let's not leave out the maria equipped and functioning cab that has that little switch on the maria to speed it up.....about this I do not lie......some cabs have a jacked up meter such that the driver throws a switch and that maria starts really moving.....beware......they ARE out there.....LOTS of them.....
A metered cab ride from the Del Rey to Sportsmen's Lodge in the day should not exceed 600C.

Also, MexiBob....it's ALWAYS best to give directions in Spanish rather than saying a Hotel name. If you just give the hotel name, you're likely to get driven all over hither and yon.....keep a couple of the hotel cards (both the Dunn Inn and the Sportsmen's Lodge) as I believe those have directions in Spanish on them.
Sportsmens Lodge se encuentra a 200 metros oeste de la rampa del hospital Calderon Guardia y 25 sur, calle 13 entre Av.9 y Av.11 casa 949 en barrio Otyoa
I can't find directions for the Dunn Inn on their web site. Give them a ring and have them email directions in Spanish. I'm sure Boyd will help you out. Toll Free: 1-800-545-4801
Now going to the Del Rey .....It's a bit different and you can tell the cab driver you want to go to the Del Rey. Leaving the Del Rey to go back to Dunn Inn: Follow Pop's advice above AND DO NOT take a cab that is in front of the Del Rey and parked....they're the one's Pop's is noting you do not want. Rather, grab a cab that is on the street right out the door from the Blue Marlin Bar inside the Del Rey....you'll see this entrance/exit once you're there.....you can get a maria (metered) equipped cab on that street most any time of the night and day.....
Have fun and it's my suggestion you WRAP THAT RASCAL and play safe.....
