Another key surprise party idea is to make sure that whatever you do you do not change any routine that the guest of honor is used to. If you are not normally in the habit of trying new restaurants then do not arrange a surprise party at someplace you have never been. If you do not normally go to a particular friend’s house for a night out then do not plan the party there. Always plan a surprise party around the guest of honor’s routine, that way they are genuinely surprised when there is a party. Make sure you plan it around a routine you can count on because if you plan it around the assumption that you can get the guest of honor to break routine then the surprise is ruined and now you have to almost tell the guest of honor what is going on just to get them to come to their own surprise party. So the lesson in this is for any surprise party idea always use the guest of honor’s routine as the schedule for the party otherwise the cover will be blown and the surprise is gone. If the guest of honor thinks they are just going out for an evening like they always do then the surprise is that much more genuine.
Never introduce new people into a routine to try and help pull off a surprise. Introducing someone new to the guest of honor’s routine automatically puts up the sensors and tips the guest of honor off that something different is happening and something may be going on. If your group is used to introducing new people then that is fine, but this all leads back to maintaining routine and keeping the surprise party a surprise. Someone new in the group automatically indicates that something is different and something may be going on. So save the new introductions for after you have sprung the surprise otherwise the secret could be ruined.
