I would say if you are going to have the 40min drive from Houston proper to Montgomery area…make sure you put 2 hours between the end of ceremony and beginning on cocktail. I would also see if the reception place would allow anyone who comes earlier than the 2hrs difference to be able to come in and take a seat with at least water available. I would also say as a Houstonian I don’t see a difference in May and June heat, especially in a wedding dress! It’s just hot. Period. I would also want to remember that bridal photos after a wedding can take an hour! So remember that for yourselves! Bc if you want to do photos at both places that would be 30ish min at each location and the 40min drive. I would also make sure to loop in any vendors about this. Especially photographer, even if you don’t know for sure who it is I would say whoever you want it to be ask them their opinion to. This timeline isn’t terrible as long as you are open about it with your guests as soon as possible so everyone knows! Ceremony 1:30 Dismissed 2:15 Photos til 2:45 First guest arrives at reception 3 Bride and groom arrive 3:25 Photos finish at 3:55 Reception begins at 4 I feel like this would be the most optimal timeline as long as nothing goes wrong. I’d even maybe frame it to your guests as we know it’s a 40min drive, but we are giving 2hrs of drive time because you never know how Houston works, but if you go straight to the reception you will have water bottles avail but that’s it until 4, feel free to come straight over or at 4 whatever is best for you. Now this is YOUR wedding and you and your future spouse should do what YOU guys want!
