I'm trying to plan a party...?

Hi All.

It's my mum and dad's silver wedding anniversary on the 4th may and i'm wanting to plan a party for them but it would be on the Saturday after which is the 8th May. I'm not sure where to start really and i'm only 17 so don't have to much money to spend on it. I'm not sure whether i want to hire somewhere like a hall and then cook all the food myself or whether i want to take them to a restaurant with a lot of there friends. I want to get table decorations that will be silver or say 25 on them. Also what food and drink would i need if i hire a hall. Do you think i should hire a hall for afternoon and evening as some people will be working on the day so may only be able to come in the evening but then we have family who have young children who would be coming to. So what do you think?

Any help is much appreciated.

Thanks

Ruth. x
