Yes, Margarita has great prices on her car rentals but her attitude and customer services skills lack greatly. I would much rather take my money to someone who is friendly EVEN if i have to pay a measily 5 dollars more! First off, i get there and she was reluctant on granting me her online prices stating that those prices are only if you reserve WAY in advance. Then, when checking out, i was short by a hair on gas and she made a huge deal about it and made me pay an additional fee. In the end, i found that if i would have gone with the street vendor that was nearly kissing my feet for business, i would have paid the same and not have had the disgust of dealing with such poorly mannered person. I advise anyone who is going on a vacation to Cozumel to take the offer of $35 per day given by the street vendors by the ultra mar ferry dock and avoid dealing with ignorant people.
