Since I've been looking at venues, I'm starting to wonder if I should try a tented wedding location because I do not want a traditional ballroom reception and am having a hard time looking for an indoor reception that meets my vision (and budget). My biggest concern about having a tented wedding is that I am doing a July wedding in NJ and am worried it will be too hot. Anyone who has had a tented summer wedding please let me know your experience with this and suggestions you have to keep it cool! Thank you!
Also if anyone has suggestions for NJ venues for about 120 guests let me know

I'm looking for rustic/historical venues
Re: Too hot for a tented wedding?
Where in New Jersey are you?
It will be hot, even if it is air-conditioned. I would move forward with extreme caution if you are set on it being outside. I went to a tented wedding the last weekend of August, but it was only the reception that was tented, so we were outside in unshaded grass during the hottest part of the day for the ceremony and cocktail hour (for 3 1/2 hours). We were all sunburned and disgustingly wet (semi-formal affair, poor FI couldn't take his jacket off because he was embarrassed by how soaked his shirt was). GM was in a wool tux (95 degrees with heavy humidity) and had a morning full of drinking. He was extremely dehydrated and passed out....
Try your best to keep everyone hydrated, shaded and cool. The last thing you need is a hung-over GM passing out in a wool tux. Opting for an evening wedding will help, as the hottest part of the day should be over. I've seen weddings where they provide parasols, fans and water to guests as they wait for ceremony.
Since you are still looking for a venue location for the reception, you may want to also look at your local board. I don't know if it's an option where you are at, but try calling local historical houses. There are 2 historical houses turned into museums within walking distance of my office. We've hosted fundraisers there before, and all they ask is for a donation to the museums. They don't advertise that it's an option, but if someone calls and asks, they accommodate the event if they can.
I live in North Jersey near NYC, but our families are from south/central Jersey so I'm looking all over the state. I'm going to try and see Oakside Mansion in Bloomfield soon, they have a permanent tent so I will ask if they have air set up or their options for that so I know if it would be a possibility.
No matter what though, you need a plan B for both ceremony and reception. Not just because of temp, but because of rain, humidity, bugs, mud, etc.
