I have the choice between these 2 resorts through RCI for the first week of June. I have stayed at HGVC and have read that Vistana has a ton of children's activities, we have a 9 year old. I have the option to get a 6/6 or an 8/6 with Vistana. Is there a way that I could chose one of these to get in a newer unit? This would be a Sunday check-in. Any info or suggestions would be great!
