Me too ... been like this since at least yesterday. Tried webchat last night who were utterly useless then rang the UK telephone booking line who said they had had many complaints and had reported it to tech who were working on it ... perhaps putting back the old website while they do some PROPER testing before going live might be a good idea ?
To any IHGService Lurkers reading this .... have you any idea how annoying this is and any idea how much money it must be costing your company ... SORT IT OUT.
