I must have missed that your kids are older... Because it sounds like you will regularly be going at least with 5 "adults" and up, and may in the future be bringing grandkids, you should keep in mind max occupancy in the 1br (possible if you are only taking your 17, 20 and 25 year old) and the bathroom situations.
AKV Kidani and BLT can both accommodate 5 in existing bedding in their 1br, and 9 in their 2br, AND they have an extra full bath. So the 1br have 2 full baths, and the 2br have a luxurious 3 full baths. Unfortunately, BRV and CCV accommodate only 4/8 in their 1br and 2br units, and don't have the extra bath. AKV and BLT are also among the more cost-effective to own resorts as well. OKW can also accommodate 5/9 but I'm not sure if they have the extra bath.
Both links I tried to post don't seem to be permitted, but you can find that info online prett easily.
