HI
I threw my sister in law's baby shower last year. I had it at my home, although not a big house and 50 guest showed up.
it turned out great. I did a jungle theme. I got a bunch of stuff animals, like lions, monkeys, tigers, ect.. I hung the monkeys from (Christmas garland) the green stuff that looks like real pine, took some tiki tourches from the backyard and criss crossed them, hung animals from my plants in the house, got a jungle theme cake, had jungle theme balloons, and covered the mother to be chair in jungle print and of course served snacks and sandwiches from like port of subs. I also played jungle music in the back ground. She so loved the party and thought I was decorated so cute, and of course I gave her all the stuffed animals to take with her. Home is cheap and you do not have to worry about carry a much of stuff to another location. I am now planning a bridal shower for someone else and she asked if we can do it at my home...Remember,
you must think about the mother to be and how many times she may have to use the restroom and that she has something comfortable to sit on. Good luck...and have fun.
On other suggestion is, you might try a restaurant like olive garden or something in that venue that will let you have a baby shower.
hope this helps.
