Congratulations and welcome home!!!
Something to think about - you might want to consider breaking down that 350 point contract into either two 175 point contracts or three contracts of 150, 100, and 100.
Your guide can do it for you easily and it won't cost a penny more to do.
The advantages would be:
1) you could leave separate contracts to your children one day
2) if you ever had to sell, you could sell one contract and keep the others - if you had one large contract, you would have to sell the whole contract
Enjoy many years of wonderful vacations!!!
