With 2 kids (5yrs & 2yrs old), we will go to Kyushu during Feb 7-11. Because the weather is still cold (0-7C), can you please advise the details of "衣着就要保暖, 但千其唔好着羊毛底衫, 所有室內地方包括車廂都開暖氣, 外套最好防風防濕防雪, 鞋要防滑". If possible, please recommend the brand / type of clothing and where could we buy them...
it is pretty messy now because we originally plan to drive but because of snow we have to take JR...never travel by JR with kids before, now we have to check everything very detail and try to minimize our luggage size/volume :(
