Winter wedding shower venue ideas

I'm sorry but your sister is out of line with her "guidelines." 60 guests is a very large number for a shower, and you can only afford what you can afford. Typically the bride only provides the guest list and the hosts handle everything else. For a shower as large as 60 people, on a budget, and in the winter, a community center or reception hall is the most logical solution. Or, since the groom's family makes up the majority of the guests, are some people from his side able to co-host with you? A shower for 60 guests at a restaurant would probably run you $3k at the very least, whereas you could totally pull off a shower for less than $1k at a community center or reception hall. Have you explained this to your sister? You're not an ATM, and she can't demand that you spend money you don't have. Hopefully she will see this and be willing to compromise--have a 60 person shower at a community center, or lower the guest count to somewhere around 20 if she wants a fancier venue. Good luck!

I visibly pulled back when I read 60 guests. That's very very very large for one person to host as a shower. I would ask her to go back to the beginning with the guest list, and hold the number at something like 15-20.

I agree with the other poster's advice here. If your sister is set on having that large of a guest list, I think the path of least resistance would be to show her pictures of venues you can afford when they're decorated for events and explain to her that you'll do your best to make them look nice, but that that's what your budget will allow for. I also think asking someone on the groom's side (his mom, an aunt, a sister, a cousin, etc.) to co-host would be a good idea since their side is making up so much of the guest list.
