Please BEWARE Safety Deposit Boxes are not always safe as has been pointed out recently on this forum.
They are usually located in reception areas easily accessible by almost anyone passing by not always
Hotel guests and you have no idea how many keys are in existence or who has one.
Best to take only a minimum amount of inexpensive jewellery leaving more valuable items at home,keeping debit/credit cards with you.
Your payment of approximately £30 a week for a Safety Deposit Box comes without any guarantee that your items will be protected and if the box is attacked you will receive compensation.
