It looks as though an airfare-plus-hotel package for a hotel not really handy to London might be cheaper than just the round-trip airfare. Are there likely to be problems, like weird extra charges or losing my return ticket, if I pay in advance for a round-trip ticket and hotel room, and just never turn up at the hotel? (I'm not going to challenge a hotel bill for the amount agreed and charged in advance; I just wonder whether this is like airlines cancelling your return ticket if you don't use the outbound flight.)
