Oh no, i think most of us have had a tanning disaster so i can tell you the best thing that works for me when i have this problem i make a paste of sugar and lemon juice. the sugar is a exfoliant and the lemon juice is the acid that removes the colour.
Spray tans are great for a spur of the moment event but if you want a more longer lasting tan i would use one of the gradual self tanning moisturising creams there fab. My personal fave is avons skin so soft one, smells gorgeous and is a excellent price
