We had plated service and it was fantastic (part of the package). Its true you don't need to send your vendors other than the baker who will create the cake design with your colours unless its different from what your vision.
I did but as said already it’s not necessary . The only reason why I gave one to the DJ was because he was being invited regardless and it made me feel better that they had one .. No excuses as for my officiant they were a family friend ...
They are your vendors and have already kept your date and will cater to you on your day. The only vendor I gave the card to was my baker for the colours to match based on the fact the thank you cards were the same design.
I'm not since they know the date and that they need to be there. The only one who is getting an invite/save the date is my hairstylist, whose also a close family friend who will be going to the ceremony/reception as a guest.
All vendors will get a thank you card after all is said and done.
I won't be either. The contract is good enough! However - I may send the thank you cards with a pic of me and the then Hubby after the wedding thanking them for what they provided to make my day the best one ever!
