Hey! How are you? I am a 17 year old girl, right now i am doing an exchange year in the US, i am staying in Alabama. When i finish my year my family will come over and we will have our holiday here. my family is my sister who is 15 years old and our parents. So we decided to stay in NYC for 5 days. Then we will have a road trip form NYC to LA. Then we will stay one week in LA. Can you give me some ideas of witch roads is the best. Cool things we can see and do on the way. Amazing places we should visit. Good but not to exspensive motels or hotels. I would also be really thankful if some of you have good ideas for what we can do during the week we will spend in LA. And if some of you are renting out apartments in LA or know someone who does please let me know.I hope some of you could help me! If you have some questions please ask! Thank you! Nora Samira :)
