Marina Del Ray is across the street, a couple smaller stores there like pizza, food, ect............................ also there is an OXXO store near there.
ya where they try and rip u off b/c they figure ure an ignorant tourist/college kid who doesnt know what his change should be in pesos (happened to me last year at the one further down near captains cove, guy thought he was slick giving me 10 pesos back when he owed me alot more, lets just say i didnt leave till i had all my change)
theres a little convenience store, a pizza hut, a pharmacy, a water sports place, and a mcdonalds basically right across the street. the oasis's driveway is like a mile long so it will still take you about a half hour to go there and come back.
Just hop on the bus. It will only cost you 6.5 pesos which is about 65 cents and will take you down closer to Party Central where you will have more of a selection. Or, take it all the way to Wal-Mart for an even vbetter selection and price.
