What should I pack for a holiday in Mallorca during September?
The weather in September is still quite warm, so shorts and t-shirts along with swimwear for the beach during the daytime, however for going out to dinner, we found that the people in Mallorca dressed up a little more, so it may be worth packing a few nice items of clothing for going out, although i'd probably give high heels a miss as some of the cobbled streets could cause problems! It can turn a little chilly later in the evening, so might be worth taking a cardigan or jumper.
