Did not see one in in the Cancun Hotel district, but there might be one kicking around. Definitely not within the immediate surrounding area.
definitely not walking distance. There's one on The Forum By The Sea (where Coco Bongo and Carlos N Chalies is) it takes about 15 minutes to get there by bus.
I have been to the Starbucks in Playa Del Carmen, & the Cancun airport, But have not seen one in between. Sorry...Maybe you would Like a Tequila?? K@
Fresno - hop on the bus. Right downtown before all the bars. U will c it from the bus. I went twice last year in the early am. The cancun bus system is safe and reliable. Todd
The rooms do have coffee makers, so it might be easier to bring your own coffee and brew it in your room. Don't forget filters though.
