You can find many designs for 50th birthday invitations that are meant for surprise parties. It is important if you are planning a surprise celebration that your invitations reflect this message. You should be certain that you give a number for RSVP that the birthday honoree will not answer.

Your guests should be told on the invitation that this will be a surprise party, so they can be sure not to spoil the surprise by mentioning the party to the birthday person. You should also include a phone number for any special directions or other requirements by your guests. If the birthday honoree is your spouse, you should be sure to give a phone number that this person will not answer, so as not to spoil their special surprise.

Be certain that all guests are informed about the surprise and give them a specific time to arrive at the party location. You should strive to have all guests at your party location at least thirty minutes before the birthday honoree arrives, so that you can be sure everything is ready when the party begins. Have this information printed on your invitations as well so that your guests are well aware of all instructions.
