Start by gathering everyone who will be attending the party. Brainstorm some themes and ideas of what kind of activities you could do to make it interesting. Decide on a date and time where everyone will be able to come and plan for food, decorations, and music accordingly. Send out online invitations, announcing the surprise party so everyone has enough time to prepare for it! On the day of the surprise party, hide inside jokes, gifts or even cards from your friend all around so when she arrives everyone can rejoice her arrival! Lastly make sure you have plenty of cameras around because it'll definitely be an unforgettable moment for everybody.

Planning a surprise party for your best friend's birthday can be fun, but it requires careful planning and some strategic maneuvering. Here are a few tips to make sure that the surprise is pulled off perfectly. 
1. Choose an appropriate venue - Select a location where your friend would never expect a party to take place. Make sure that you have access to the space as well as adequate storage for presents and decorations if necessary. 
2. Invite guests - You’ll want your friends’ reactions when they discover it’s a surprise party to be captured on camera so send out formal invitations letting them know exactly when, where and why they have been invited!
3. Hide the décor - Keep decorations away from areas frequented by you or your friends - they may notice something is amiss otherwise! Hide anything that might give away the surprise in unexpected places, like in books or record albums, so no one has an opportunity to stumble across evidence of the impending celebration..  
4 Prepare presents – Organize presents into ‘go-bags’ containing everything from wrapping paper, cards and gifts all labeled with who bought what gift; it saves time (and stress!) when organizing present delivery throughout the night! Additionally have back-up items ready in case any person doesn't manage bringing an gift on arrival day; last minute pick-ups are not encouraged however extra snacks & drinks won't go amiss either !  
5 Cue the music – Put together an excellent playlist of songs dedicated specifically towards this moment – keep people engaged during preparation & presentation moments without having them think “What happens next?” Set up some props – create creative elements out of items lying around such as posters / signs suggesting its special moment !     Lastly let all guests know via secret code words/hand gestures etc when its truly game time…Go Get Them Surprise Parties Ahead !!
