We sent out our save the date message in a bottle about 3 to 4 months ago. I didn't include a letter with many details since at that point we still weren't sure what resort we were going to be staying at. We are having a nonresort weddign so our guests have the option to stay any hotel they choose. They don't necessarily have to stay at our hotel so I didn't think it was as crucial for me to include that information yet, especially since it was still undecided. Basically our save the dates included the date, the location and our web site.
Then, as soon as I found out what resort we were staying at, I updated our web site and sent out an email to all my friends and family with hotel info and travel agent's number. I forwarded the email to my fiance and told him to forward it to his people. Now 5 months to the weddimg and very few people have booked and I am afraid I may be the reason for the low confirmation. Maybe my email was such an informal way of communication that people didn't really take it seriously. I figured people could always look at the web site and realize we have booked our hotel but maybe no one is looking there.
Should I have sent a follow up letter instead of an email


Should I still send one now with the travel information and remind people to book if they are really considering coming

Am I just silly for worrying

Don't get me wrong if people are just being lazy and haven't purchased their tickets, that's fine with me but I just want to ensure I gave them all the information they needed properly.
Thank you so much for your input!!!
