Don't feel bad. Sometimes I get a futz in the brain and fail to look outside of the box which leaves me in a "what were you thinking?" moment.
I would say go with the AKV Kidani standard.
1. As you've mentioned, the kitchen saves a lot of money. And honestly, sometimes you just don't feel like eating out three meals a day.
2. The extra bathroom is priceless. Especially when everyone is trying to get ready to hit the parks in the morning.
3. I think your parents will love the atmosphere. It's so nice to go downstairs in that public room and sit outside or inside and watch the animals.
Also, if you are concerned about how many points it's going to run you, you might want to consider 5 or 6 nights and cut off a Friday or Saturday night.
Have a great time.
