A trip for my family

Hi my wife has cervical cancer stage 4. And there is not much they can do they said. They want her to enjoy her life with her kids and me. They have giving her 3 to 6 months to live and 3 months has gone by. I wanna take a little family trip together while we still can. We have 2 boys together. Trustin who is 8 and Jace who is 9. If you can help in anyway please do. Thank you and God bless. also if you could maybe give me an idea where to go. or where would u go if it was your last trip ever. we have never been out oklahoma. and we been together 10 years. i just want the chance to have a great time with the family. maybe it will clear our minds a little and maybe relief some stress
