June to August in Europe is known as High Season (which means you can expect wonderful summer weather but the downside is quite a few crowds). Any destination in Europe will be a great destination during high season.
If you really put your mind to it, and constantly expose yourself to a language then you may find that you can speak it with relative ease within about 6 months, although as mentioned before, you would really need to be living in a country that speaks that language in order to get to this stage.
I've heard something like 600 hours to learn an easier one like French. I've had somewhere around 400 French and 300 Spanish -- you're probably farther along than I -- and in both cases, I can get the gist of a written or plainly spoken text, depending on vocabulary.ell, it takes a long, long time for a regular adult to become fluent at a second language they're learning through books and classes-- probably years, plus eventually some time spent in a place where the language is spoken. But it's not all or nothing. Every stage along the way is valuable.
