Once in a lifetime 7 day trip for two through an adult Make A Wish style program. Where should we ask to go?

My wife was selected for a trip through a program that is basically like Make A Wish for adults after she dealt with a spinal tumor (she is all good now!). They do not tell us the exact budget, so we are trying to figure out what is realistic without accidentally under asking. It has to be within the next 365 days.

They gave us examples of trips other people have taken, including Bali, Spain, Greece, Honolulu, Maui, Croatia, Vietnam, the Great Wall of China, Germany, Rome, Tahiti, Paris, Tokyo, Portugal, and Israel.

The trip is for 7 full days at the destination. Travel days do not count against the 7 days, so even if it takes a day or two to get there, we still get the full trip once we arrive.

We have to stay at a hotel, resort, or all inclusive. No Airbnb. They also give around $1,000 for incidentals, food, and baggage. If we choose an all inclusive where food is already covered, the incidental amount may be closer to $500.

Based on the trips they listed, we are guessing the budget could maybe be around $10,000 to $15,000 for two people, but we do not know for sure.

We are open to almost anywhere, but we are thinking about places like Bora Bora, Moorea, Tahiti, Maldives, Greece, Italy, Hawaii, Japan, Croatia, Bali, etc

We submit 3 places we’d like to go ranked in order of preference. Our top 3 as of now are bora bora, Maldives, and Zanzibar

If you had one shot at a true once in a lifetime trip for two, where would you go? We are looking for something that feels special and hard to recreate later, not just a normal nice vacation.

Also, are there any places you would not use this opportunity on because they would be easier to do later on our own?

TLDR:

My wife won an adult Make A Wish style trip after dealing with a spinal tumor. It is 7 full days at the destination, travel days do not count, and the budget is hidden. Past trips include places like Tahiti, Tokyo, Greece, Bali, Hawaii, and Europe. Where would you go for a once in a lifetime trip for two?
