I stayed for 1 night a couple of years ago and thought it was extremely good value for money so I've 5 nights booked from 29th october.
Vala's experience is dreadful, both theft and hotel's behaviour, unfortunately it's not an isolated incident i have read similar stories from other hotels including the Disney hotels.
I take a minimum of expensive items, so i can be pretty sure they'll all fit in the room safe, but i've always left lanyards in the room, i would be gutted if i lost any of my Maleficent pins, so after Vala's story they'll be in the safe next time too.
Did you have a ground floor room Vala? Was there evidence of a break in, window open or anything or do you assume they had a room key ?
Not sure if Kyriad has interconnecting rooms, but something i always check is that the interconnecting door is locked, ever since my son and niece ended up in the room next door at Hotel New Year 'Look mum more beds'
