Take the tram from 12th & Imperial Station to El Cajon Station. Take the bus from Tijuana Central Bus Terminal to San Diego. Hit a 'feature', won 10 free games and won 0.96 cents (did not cover the bet). Bus, tram, line 864 bus, line 838 bus 5h 32m. Played slots- VERY VERY tight- saw very few winners. Had a drink ( $6.00 for a well drink including discount)) in the Lobby Bar while we played Video Poker- had appetizers which were DELICIOUS- service was excellent. The RV lot is just above the employee parking area. Alternatively, you can take a vehicle from Chula Vista to Viejas Arena via 12th & Imperial Station and SDSU Station in around 1h 12m. Tickets cost 1 - 5 and the journey takes 49 min. Did notice that the shuttles drove through the lot every 15 or so minutes. San Diego Metro Transit operates a bus from 8th Street Transit Center to Montezuma Rd & 55th St every 30 minutes. I notice that the employees did not tip the driver so I am reminded that to do so is a personal choice. Uncomfortable with 'names' being used to describe shuttle drivers- they are just doing a job like the waitress. Yes, we did 'tip' him which is our choice. Shuttle driver came immediately and we asked he come back at a certain time (which he did). Trucks (2) and buses (which left by evening) were parked on other side of street. Lot on east side of new hotel and casino is slightly sloped but our jacks got us level. Sign entering RV/Truck parking area reads '24 hour stay'.
