I haven't made any plans really. We have a big backyard so we could do it here. For their third birthday we were going to rent a pavillion at TY park, which has a water park with slides called Castaway island it also has an area for young kids and their parents. When I called they had a meeting cabin (WITH A/C) which needed a larger deposit but would be cheaper to rent so we went with that it was also close to the water park being the middle of July in south Florida I thought everyone would be over at the water park but with the A/C everyone stayed comfortable enough to stay at the cabin. It was great party, everything was the Wiggles, it was before they were on The Disney Channel so all the merchandise had to be purchased from their AUS website. They loved it, I made a pinata in the shape of a hot air balloon in the wiggles colors and cut up the leftover wrapping paper with their pictures on it and glued them to the balloon part. I wanted some figures of the wiggles to put in the basket so they could but they didn't have any so we went with the pictures.
Last year we had it at this house and there wasn't any theme they just requested a Hambuger cake so I made them one. I make different cakes the one for their third birthday was a flower bed with worms and flowers made out of candy. I made one for my sister's son in the shape of "Clay" from playhouse disney 3D not flat. I also made a cross for his Christening. Baby blocks for her baby shower with her sons name spelled out on the blocks.
I like making the pinata's too I made a blimp for Dh's birthday the twins said I had to

and I made JJ the jetplane for my other sisters little girl and a sun for the one I made "clay"for.
I was thinking of Chuck E. Cheese this year if we could swing it financially. I do not know, if not, we will do it here it looks like it may be a pirate theme this year. I can do a Hidden treasure hunt around the yard and house. Make stones with things inside for them to find and maybe a pirate ship for the pinata. The cake I was thinking of a treasure chest.
What about you do you throw big, modest of family parties?
