Luckily you are visiting with children so you only need to be able to communicate on a certain level. I would go to the library and check out some children’s books in Spanish. Read them aloud to yourself to get used to the difference in accents. Some of the books even have English and Spanish translations.

I recommend “Buenas Noches, Luna” or “Good Night, Moon” for a start.

The best way to be honest (for it has worked for me also) is too memorise verbs and verb endings (especially the irregular verbs since they are used the most in the language), when to use ser and estar etc. Once you know those basic, fundamental elements (and a whole range of vocabulary in general), there’s no reason why you shouldn’t be able to speak Spanish fluently by then. It’s seems harder than it actually is but trust me, if you’re devoted enough, the learning of verbs may take even as little as two weeks to learn.
When learning a whole new language, you have to be passionate about it; once you love and enjoy it, then there should be no worries whatsoever.

I hoped that helped.
