Hi there. We are coming over to Las Vegas from New Zealand to get married in September 2019. We are expecting approximately 60 - 70 guests. I am in love with the desert weddings I've seen on Instagram, but worried about the heat - will late September be too hot? I also wondered if anyone has any insight into permits for weddings in Red Rock or Valley of Fire and whether it's possible to organise these yourselves or which vendors to use? Thank you in advance.
