The Hilton Slough (so-called T5) has already moved to these hours and reduced their food offering. I can't think of a time when I've been in an airport hotel before 6pm, often it's lucky I'll arrive with about 20 or so minutes left to enjoy the lounge so with the new hours I'll just have to assume I'll never make the lounge so remove it from the decision making process of where to stay at Heathrow

The Hilton T4 used to offer:
- A good Chinese restaurant
- Pool with sauna
- Lounge drinks 6 - 8 with a better selection than currently
- Better food in the lounge than they do now
- Haggis at breakfast (although without the haggis it's still a very good breakfast).

Hilton T5 used to have that great Indian restaurant, a nice lounge with drinks 6 - 8 and reasonable food selections (the last time I was there they removed all hot options in the lounge).
