I did email Kings and received this response:-
Dear Peter
Thanks for the email. Sorry if you did pick up some kind of bug but I would
have to say we have had no reports from other guests and most stay with us
longer than just the one night as you guys do . Also ths staff , including
myself and my nine month old kids live here and drink the water all the time
and we have been fine . Our water sytem is checked once a month by a
specialist company and they also have reported no problems .
Again , sorry to hear you have not been well and other than that I do hope
you enjoyed your ride .
best Regards
guy
So if anyone else want to email him as well, feel free. kings [at] yha.org
I am still suffering violently atm.
