Anastacio is right on that.
while it was the opposite 10 years or so ago,
Today's Foreign receptionists are a Rare occurance, they exist, yes, but a rare spezies. Dominican Front desk workers have usually a base of at least 3 Languages, not always fluent in those, but the Variety for communications makes the Deal on such Job in a Tourist Area where the Guests come from absolutely All around the Globe. Payments for such job on average range10-18K Pesos per Month, I would never have heard of Part Time Jobs for such at the Resorts, it is Full Time Jobs, so You would not be able to attend a real school aside such Job.
similar for Guest Services Jobs, just here often more Languages are required and need to be spoken and written better, payment ranges the same, shifts of 10-12 hrs are not out of the ordinary.
and then the Locations.
the DR South Shore around Juan Dolio and Boca Chica is Today's not in it's best Shape sorrily, name it a Deep Recession that happened there since a decade and still not stopped the Run Downhill.
in a Large Tourist Area like Punta Cana on the far East you may not find the Kind of School or Univercity etc You plan to visit, and anyways the mainpoint is:
such Resort Jobs would not allow to attend a real school aside of such Timeintensive Job.
Tourism is a treatmill, on this Isle as a Employee You always work much longer Hours for much less money than usual in the US or any western European Country.
for a Curriculum Vitae you find the appropriate examples here
Modelo Curr?culum
they are perfectly suitable for this Country.
good luck
