I find XMAS market purchases little in size. You may want a separate suitcase for food products because many of the XMAS markets have wonderful food products that can't be shipped via hand luggage. I tried to bring things back and they were confiscated. But there are wonderful cheeses, pastas, drieds meats, confits, candies, spices and knick knacks. I love the hand blown crystal candle holders. So you have to bring one hand luggage too for fragile things. I stocked up on wonderful marinated mushrooms last year, but my sauerkraut didn't make it!! The cookies and cakes are usually to die for. I bring back loads for gifts.
