When my daughter turned 18 last year, she's not into drinking, so for the day before the day she had a birthday at a restaurant with family and had a photo cake done. Then the day after on her birthday it landed on the national fireworks championships. There's 6 dates in the year. We went to Ragley Hall in Warwickshire and we took a picnic with us and folding chairs. it was great fun. Maybe have a look whats going on in March events wise. If your wanting to dress up, have a theme and go out with your mates clubbing.
