good suggestion ate juliet , thats sweet and romantic , i add this ...
b4 fiancee go shower ... make sure the bath is ready

the bathroom will go steamy

.. after that write this in mirror " Happy Birthday Honey, I Love You" fiance will be surprise and for sure ur honey will hug you tight

... prepare a dinner with candle lights , and massage his back after

... or if u still have time , write a letter and spray perfume
sorry , but thats in my mind right now

hope it helps ...
