The buses run by every few minutes and they are really cheap. I'm not 100% sure how much they cost but I know it was under one dollar. The bad thing about the buses is that the drivers dont wait for you to get seated before they take off and its hard to get off at the right spot because they dont pay very close attention to what you tell them. I rode the bus a couple times but then I just started taking taxis because they are more convinient. The drawback of taxis is the cost. It was $8 from the Oasis to Senor Frogs.
We only got a Taxi on our last day when it was raining and we were lucky not to be ripped off, but we were told that a guest from our hotel had had a few too many drinkis one night and decided to get a Taxi home, BIG MISTAKE when got out of the Taxi for a 10 minute journey not far at all it ended up costing $100.00
A BIT OF ADVISE ASK BEFORE YOU TRY
