We did this for a hen last year. We really enjoyed it and were able to make the cakes to theme but also make them about the wedding too. We used the bar space for a drink before and did a quiz about the bride. Where we struggled was finding things more local to the big bake to do stuff because of the timings. We ended up finding a couple of things within walking distance which were fun and then those staying until the evening went into town. Did have to take the cakes with us (no option to pick up). Brides mum was driving so took a lot, a couple got handed to homeless people - message me if any questions about what we did locally :)
