To have or not to have: rehearsal dinner

If you don't want one, I don't think you necessarily have to have a rehearsal dinner, or could do something more laid back and cost effective, although it is a very nice gesture for the wedding party and your parents. Have your FMIL and FFIL discussed this with you and FH at all? Traditionally, this is something the parents of the groom pay for, although its 2020 and things can be done a million different ways!

My only caveat with practicing in the morning is this: you'll want everyone to rehearse...the bridesmaids, groomsmen, any ushers/ceremony readers/etc., and the officiant. You and the girls may be at the venue starting at 10am, so practicing at 9am may be no big deal - BUT this may be stressful/an inconvenience for the groomsmen who didn't plan to arrive until 2pm or the officiant who wasn't arriving until 4:30pm.

Are your bridesmaids getting hair and makeup done? If so you might want to take that into account because practicing the morning of would take time away from that. We had our venue from 8 AM -10 PM, but hair and makeup started at 8 AM so that wouldn't leave time. We also took photos of each of us with our side of the bridal party prior to the ceremony, a first look with my dad and and a first look with my husband so all of that took up time. We had 2 flower girls and 1 ring bearer whose parents wouldn't have wanted to get them up early to practice. Some of our bridal party also had children they had to take care of the morning of the wedding. Some of our bridal party also like to sleep in so they were scheduled to get ready later in the day. Everyone also needed breakfast in the morning.

Of course you could do the rehersal on the day of! That's what we are doing too!

That's fine.
I did it the night before because it worked out better logistically for me and was more of a social aspect I enjoyed but it is definitely a money saver not doing so

Yes i think thats a great idea. Were practing the same day of the wedding event 2 hrs before it starting!

You can definitely do rehearsal the day of!

The only reason we're doing a rehearsal the day before is that our venue is kind of confusing to navigate so we want to make sure everyone is comfortable navigating it

Our venue actually scheduled this into our day of timeline because they are booked the night before our wedding. As it stands now, they will do a quick rehearsal while I am getting my dress on. It will only be a 15 minute thing just to get everyone to know the space and figure out who they're walking with and when. FH and I decided that we will find some other time to rehearse with just our officiant (my grandpa, so that will be easy) so we know what to expect during the ceremony. We are still hosting a "not" rehearsal dinner for our bridal party, parents, and grandparents as a thank you for all their help and for standing up with us during the wedding.

My in-laws are hosting the rehearsal dinner so we're definitely having one

I was listening to the Bridechilla podcast and she said that rehearsal dinners are really only an American thing? I want to skip having one, too. Everyone knows what's going to happen so it doesn't seem necessary.
