Welcome along to the forum!
Im sure you will love it... My best advice for you though, stay safe, use common sense in the regards of testing floors before using them and so on and the most important part - HAVE FUN!
Always ensure your phone battery is full, camera batteries charged, take food and drink with you and if needed money for essentials if needed. As always - stay safe and ensure buddies with you stay safe and know where you are.
