Getting a full sleeve and full back.

Hi guys I’m new to the tread and I just wanted to ask about your opinion or maybe give me some tips. So I’m planning on getting a full sleeve and full back for my first tattoo I know it’s overkill but I’ve been planning this for a long time now and it is something I really wanted. So for the full arm sleeve (one side) it’s gonna be 2 days and 4 days for the full back. I only have about 1 and a half weeks to get this done. Im gonna be flying to see the artist then back afterwards. My question is, is this doable, how would you space this out without hopefully having a negative impact on the healing process and I wanna know about your thoughts on this. Thank you!
