In my opinion, gift them the money you plan to pay for their holiday and ask them to spend it on whatever they like. They will be 100 times happier and sleep peacefully for the next few years without worrying about having to pay for that bill, this bill, a gas bill, an electricity bill, etc. out of their own savings.
If you still wish to send them abroad, do only a package tour since this is their first international trip. Most of the obstacles involved with a foreign trip will be sorted out by the tour operator, and you can avoid getting blamed for pushing them out for this international trip and stressing them out.
