A Halloween boat party in central London was exactly what my friends asked for. We had an amazing time on board the viscount, all of our guests dressed up in scary costumes as well as having the boat decorated the perfect Halloween boat party. We asked for custom cocktails which were all amazing and perfect with the theme. Our 200 guests were so pleased with how the Halloween boat party event turned out; they want to do something similar every celebration which is great, so will definitely be using Thames party boats in the very near future.
