For any wedding, whether near or far, there should always be some sort of transportation or hotels lined up for your guests if they would like to stay overnight. In addition to those people, the bride and groom traditionally will stay somewhere nice afterward and maybe some family members will stay, too, in hopes to see them for breakfast the next day before they are off to their honeymoon.
The majority of weddings I have been to have had a hotel block reserved unless the wedding was early in the day. I haven’t personally stayed in these hotels because the weddings have been near my home. However, I think it is nice to have the option.
I know a good amount of my friends will want to stay overnight for my wedding so they won’t have to worry about driving too late. Our wedding is at The Engineers Club in Mount Vernon. We looked for rooms at Peabody Court, which is within walking distance, but the suites were already taken, so I think we've decided to block rooms at the Tremont, which is really nice. In order to do that, we'll need to set up a shuttle bus, though.
I think this will work out well, but the hardest part is figuring out how many rooms to block off. I think you can add or take away if it is not the right number but that’s the next thing on our list to take care of.
