Living expenses

First off welcome to the forum.  Where in the DR are you moving to?  You should do fine on that budget depending on lifestyle.

There are multiple flights to multiple European cites from multiple air ports here.  It all depends on where you are located as to what cities willl be easiest to get to.  The only cruise that i know of that you can board here on a regular basis leaves from La Romana on the south coast

The public schools do not use substirute teachers unless for a long posting but some of the private shcools do.  You will need some typr of teaching certificate and to work here legally you will need your residencyand cedula.

There is lots of good information on this fourm just read, read and read some more and come back with questions.

Good luck
