LA Galaxy star Jonathan dos Santos is havin' one helluva start to his 2020 ... hitting up the beaches in Mexico with not only one gorgeous bikini-clad lady -- but TWO gorgeous bikini-clad ladies!!!

The 29-year-old MLS midfielder is enjoying his time away from the soccer field this week by catching some rays in Cancun ... and the views are spectacular.

Oh yeah, and the beach is pretty cool lookin', too.

JDS has been playing in LA for 3 years now ... and has recently said he wants to retire a member of the Galaxy when it's all said and done. We take it his retirement plan involves more beaches and babes.

In total, there were more than 2 hotties with dos Santos in the water ... but that headline wouldn't have been as creative, now would it have???
