We are doing ours a a park shelter house (if it happens to be cold or raining it's not a problem)
For us it works our great because our family doesn't live near us... so we are going home to them. We have the shelter, it has tables, electric, and I think stove and a fridge! Only cost us $40. The park is right there so we don't have to worry about activities for the kids either.
I can't do it at home my family and my hubby's are big, my babies have a lot of cousins hehe so I was thinking maybe an a park but what about wether ? Her b-day is in September 25 you think thw wether will be good ?
