Although wedding guests are likely to be more relaxed than the bride and groom, they will still have their own share of anxiety and excitement. Soothe them with a set of luxurious toiletries more likely to be found at a spa than a wedding. Here, a simple box lined with a cloth contains small indulgences such as scented bar soaps, bath salts, bath gel, lotion, candles, and tea bags. For guests who don't travel well, include a small container of massage oil.
