Is it worth paying for the breakfasts - are they big buffet breakfasts which will mean no lunch needed, or a bit meagre? They aren't a particular bargain, but then breakfast out never will be I guess...
Also if I book a saver price for a family room for 7 nights in a city centre 6 months in advance an I fairly much guaranteed to actually have the room when we arrive, or are there horror stories of this type of booking being bumped for higher paying last minute guests, as happens with some similar chain operations? Will it being a family booking for 7 nights make it more secure than the single night stop overs which often seem to get bumped to a less desirable location by some budget hotel chains?
