If you have no one to look after her and a pet sitter or small animal boarding place isn't an option, then definitely take her with you!
Its not ideal, I've never travelled with a hamster for more than 4 hours in a day. But if its an 12 hour trip and then 2 weeks for her to settle before the next 12 hour trip, then that's not so bad.

Hopefully, if shes good with noises, she will sleep the majority of the trip. You need to be prepared for the possibility of her water bottle leaking and maybe provide an alternative like cucumber for moisture. Though do make sure she has access to water at some point within that 12 hours. You also need to try and keep the temperature fairly regular.

Hope you can work it out and you can both enjoy the trip x
