I was wondering if it would be impolite to send out STD without a specific date and ask if they would be attending...it will be a DW in the Dominican in March 2010 and we would like a rough number of how many would be attending......we will be sending out formal invites at a later date. We thought this would give ppl time to either save money to go / or reserve the time off....Are we being rude? My older sister seems to think so. I would appreciate youe input!
