That are all awesome ideas!
I think Beach Vacation is a must and hope that if they make it they can/will implement at least some of your ideas.
I'd love to have Winter Vacation as it would be something almost (apart from The Sims) completely new. A Yeti NPC would be very interesting indeed!
The Sport/Outdoor Fun idea sounds nice too and could be a possibilty to add plenty of new activities for sims of all ages + pets.
Having the opportunity to have the sims persue hobbies like crocheting, sewing or doing pottery would be great. I really liked it in The Sims 2 to be able to craft objects and clothing as the skill built up. Also an activity table like that would be much appreciated. I was very disappointed when I found out they couldn't draw on the one in The Sims 3 even though there are sheets on it.
Yes please to an Oldies music station.
I really like that you always thought of toddlers and children as well. The lists are very well detailed - I hope they see them. :smile:
