in the middle of june pupils get holiday for 2 months. that makes stockholm calmer and very suitable for tourists. since the whole business-life is cooling there are even special-offers for hotel-stays. check that. bathing becomes cosy not before end of juli.
midsummer is the biggest feast, 19.june. exact from that date on stockholm city will draw new buslines through the city. can be a lot of interesting chaos . even citybuscrui.se will have to draw new maps for cruising. some very nice low frequenced and sideway-busses will disappear. thats a pity , but anyway efficiency is needed to keep the thing rolling, drop down costs etc. , though … even here the biggest cost-factor still is an incapable administration from the authorities SL . who in desperate search has left it over to my buscompany keolis to find the best ways.
