Just a note of warning to other travellers using low-cost currency conversion charge credit/debit cards expecting to gain the currency advantage.
I noticed that all of my recent euro IC bills have had the hotel effect the conversion without asking me first - so that the charges have been made in £ rather than euros. This has enabled them to add 3% to the Reuters wholesale rate.
In fairness to the properties this had been small print under my signature .... but like many others I suspect - my attention was solely on the transactions and the total which was listed as euros.
Pointless having low cost cards if IC add 3% .......
Since DCC is optional and needs the card holder's consent, I advise you to contact the hotels and have them reverse the charges. If they are unwilling to do so (which I seriously doubt within the EU), I would have your credit card issuing bank reverse the charges and complain to IHG customer service. The hotel has no right to use DCC without your consent.
Furthermore, there are many, many other threads here on FT about DCC (scams). Shame that some ICs now also opt for this scam.
Edit: Certainly, if you haven't read the fine print and signed DCC on the cc slip, then you have no real chance to reverse the charges. For the next time, just pay attention whether the amount is xxx EUR or xxx GBP - and never sign if it is not your home currency.
