I would explore whether you can obtain enough airline miles for an award ticket in business. Hopefully you only need two?
First, I would try to figure out what is shoulder season- a good time to travel but not super peak time.
Then, I'd go to something like kayak or Expedia and search for flights for similar season this year (for example it you are thinking next Sept, I'd search this Sept). This will give you an idea of who has the best routes.
Then I'd strategize who would have the best availability using FF miles. I'm no expert on this but I understand Air France is not the best airline to fly but they have good award availability. I hear United is good. American and British Airways are decent. Delta is terrible, not worth considering. There is probably a TUG wealth of knowledge on this subject.
Next step I'd figure out if there is any way to obtain a bunch of miles quickly. Usually this is by signing up for credit cards. For example, if you and husband both sign up for personal and business credit cards, it would not be too unusual to be able to accumulate 200,000 miles within a few months. Not all cards have business versions however. Put every expense on your earning card for the time being, or use a card in which you can transfer points to the airline, like the SPG Amex. Alternatively, if you can find someone with a bunch of miles, they can book for you. Of course, you want to do something super nice for them in exchange.
Then plan on booking your airfare exactly when the schedules opens- this varies with airlines, usually something like 330 days ahead. Sometimes you have to be a little creative with routing ideas. For example, maybe you can get business class seats to Paris only. Oh poor you, stay a few days in Paris until you get your next flight leg out.
Then rent your timeshare weeks.
Making a plan like this come together is very complicated and it helps if you have miles in several systems, hotel points, and a little cash to spend. We just pulled it off to organize a trip to Crete next year. In the end that turns out to be:
1. LA-London on British Airways, business class using American Airlines miles, paying $500 per ticket in taxes
2. Four Hyatt nights in London using free nights from credit card sign up
3. London-Ath coach on British Airways using BA miles
4. Ath to Crete RT cash fare
5. Eight nights timeshare stay on Crete using two exchanges
6. Two nights Athens on SPG hotel points
7. Ath-London-Raleigh-LA business class using American airline miles. We have an overnight layover in London and will stay overnight on SPG points at an airport hotel.
