Most streaming services aren't very useful when you leave your home country. If you don't lose access entirely, you'll probably be forced to look at unfamiliar content and equally unfamiliar languages. However, that shouldn't be a problem in the European Union as of next year. EU member states have tentatively agreed to a proposed law that would require temporary roaming access to subscription streaming services in 2017, complete with the content that you're used to from back home. If you're a British traveler, for instance, you could watch Netflix's UK library while sunning yourself on a Spanish vacation.
