wow thanks for the tips guys.
Did not know that bus is 6 pesos each way. I read that all the hotels are reached by only 2 companies which charge like $14 each way.
So that is why I figured renting a car because it is only $40 so I will pretty much break even. The resort at where I stay also has complimentary parking...

As far as tours, I read that they are also $70+ which is pretty steep just to get you to the place and then back. I mean if I decide to do it by driving wouldnt I just have to pay for gas?

or are there some cheapo tour companies that can do the same for much less...
