I was wondering the same thing. I was so excited to reach 150 and I still can't see attachments. I hope they update it soon because I leave for our wedding next eek and I need the hangover kit tags!!
I hate to say it but I think it's necessary to send out invites. We worked long and hard on our website and a good number of guests never even looked at it. I know this because they called me to asked a million questions that were all answered on the website. I noticed this was especially a problem with older guests that don't use the internet as often.
I agree. I woundn't put the info on the invitations. Put it on your website and give contact details for your travel agent so people can get a quote from them.
