Accommodation, car rental companies, cruise lines and other suppliers will normally require you to provide them with a credit card when you check in. This enables you to charge items such as rooms service, phone calls, restaurant meals etc to your bill when you check out. It is also standard procedure for those travel suppliers to obtain a pre-approved credit limit authority for a reasonable amount depending on your length of stay and standard of hotel. This pre-authorisation will debit the card provided, but may reduce the available spending limit on your card. Consequently we suggest that you may wish to consider contacting your card provider to arrange a temporary credit increase before leaving the UK.
