The party packages vary, and some are much better than others.
I got into the Cartoon Network house party too, it will be my third.
The Nestle Bliss houseparty included paper gift bags, six bags of Nestle Bliss chocolates -- two each of milk chocolate, dark chocolate, and chocolate filled -- magnets, pens, grocery list pads, and a photo album for the host.
My Better Homes and Gardens Pink Plaid party package included the BH&G cookbook, 15 packages of batteries (energizer AA, I think) and 15 free salad coupons to give to each guest, a music CD, and there might have been something esle I'm forgetting.
My sister-in-law was chosen for the Gerber party. She got three cases of Gerber Organic 2-pack baby foods!!, I don't remember the flavors but they were good fruity ones I think, a bib, a bunch of coupons and gift bags, and an insulated lunch bag.
Unfortunately I didn't get in on the Margaritaville party, I think those hosts received a frozen drink maker in their packages!
The Fisher Price Playdate packages include:
1 Laugh & Learn Smart Bounce & Spin Pony
1 Laugh & Learn Fun with Friends Musical Table
1 Amazing Animals SpinninAround Musical Zoo
1 Go Baby Go Crawl & Cruise Musical Jungle
10 Fisher-Price toys to share with your guests, including Poppity Pop, Rock-A-Stack®, and Friendly Flip Phone

My sister in law was hoping to get that one too, but she didn't.
