Check in at 4pm and absolutely no flexibility at reception, in fact the woman was almost rude in her response, basically room is available at 4pm and not before. I do get they need time to turn around rooms, but not everyone checks out at noon, so there must be at least a possibility of getting a room sooner, they said they'd call if it became available, they didn't, however we managed to get a room when we returned at 1540, but even then I noticed the clock watching. Room 109 shower control would not change temperature and was too hot, hairdryer worked intermittently. TV channels - fuzzy and not visible on some channels, like rte1. Bed was comfortable, about the only positive of note.
If you let your guests into hotel as soon as you possible can, they start spending in the hotel at earliest opportunity. If you alienate guests and of course, sometimes early check in is just not possible, then they are less likely to spend on site.
