dad deserves a vacation. Time is limited

My dad has stage 4 cancer and deserves at least one vacation in his life. He's worked a hard job to support me my brother and my mom as long as I can remember. He's never had a vacation and has never left the state since I've been born. All he's had time to do is work go home work go home a slave life not actually getting to enjoy the nice things on this earth. Hawaii has always been a place he has wanted to visit. I want to surprise him with a trip to Waikiki . It won't be cheep so I need help. His time is limited so I need to make this happen fast. For 2 round trip tickets maybe 3 (one for my brother) if we can budget it in and he can take off the time id like to have 1 family vacation together. I want to do a package deal that includes round trip tickets and hotel that's going to be around 1000+ each from what I saw for just two people, plus maybe trying to get more for my brother to join also food and attractions so he can check out some of the things to do in Maui. My goal is going to be 6000  so he has money for his rent when he gets back plus to help cover some medicine for him as well. Please help me make this one wish come true for him

Gofundme does take 5% but what I'm seeing is that it's taking 10%ish actually of what I raise so please let's try and get as much as possible
