Hello, thank you for taking the time to post your question!
Definitely, a tutor can be an extremely effective way to get ready for a foreign trip … rather than just reading out of a language book or tour guide you can get personalized guidance to be well-prepared for your trip. For Spanish lessons specifically, you can get practice with real conversations and improving your practical vocabulary as part of a customized lesson for your specific needs.
Hopefully that gets you moving in the right direction! Feel free to reach out for a lesson if you have any questions beyond that! :)
