My daughter's 2nd birthday's on the 17th. We're on a tight budget. What's the best idea to celebrate her bday?

She loves Barney so much and she's so into this dino! She even sings the I Love You song over and over again. My father-in-law's goddaughter gave me lil birthday balloons of different colors, balloon pump, yellow cloth, Barney birthday banners, big Barney star w/c you can hang and fill w/ goodies inside, Barney party bags to fill w/ candies, and some Barney backpacks already filled with stuff like stickers, pencils and a wallet. My hubby wants it to be held at KFC since they have a Barney theme and for us not to worry 'bout the preparations and all. For me, I just want it be held at home and we'll just order a Barney cake, rent tables and chairs w/ purple and green covers, and cook kiddie food snacks. I think party in a resto's really expensive than at home. Besides, there's not much kids we know who'll be joining so it's not preferrable to have it in KFC I think. What do you think? I'm really confused and I want my daughter to enjoy her Barney birthday party! Got nearly 2 weeks to prepare!
