I was looking at RCI, not the registry collection. For 600 points it should come with a chef, maid, valet, butler and daily massages. RCI listed ONE as AI in the US (all RCI) but when you pulled up that resort it did not say it was AI. There are some resorts that include specific types of items such as lift tickets, golf, water park and the like. Some charge extra, some don't. Smugglers Notch is one that comes to mind as providing a fair amount of additional items and charge extra for some, not for others. I haven't actually looked to see if it's on the DVC list and given we're about to board the plane for Aruba (next 30 min or so), I don't think I'll have time to do so right now. This would be a good and fair question to post for TUG to solicit resorts that have sizeable extras and whether they charge or they are included. Much like one might ask about pools at DVC resorts and then find that SAB is head and shoulders above the rest plus you can't PH there even as members unless you're staying. I hear Trapp is a nice option but not 600 points nice, I've never stayed in a timeshare unit I though was worth 600 DVC points. Maybe a 3 BR at DVC during certain times and possibly a 3 BR at the Maui Westin or Marriott peak times(I don't think Westin has 3 BR) but that's about it I can even think of for resorts I've personally seen.
To be clear, when I talk about AI, I'll talking more the cruise type of experience where at least most food, some drinks are included and as a minimum, non motorized recreation craft. I realize they will all vary somewhat. And if I talk RCI, I'll be talking RCI and not the registry collection.
