1. Cost per night
Reasonable, 40-60 dollars a night
2. Value for money
Rooms are nice, extra's like workout rooms and such are an added value
3. Service and hospitality
Excellent service, any holiday inn I have gone to
4. Facilities and conveniences
Depending on which on you go to. The express ones have wireless internet connections and fax machines. The really nice holidomes have indoor pools, sauna, hot tub, mini golf, and work out areas and are generally more expensive.
5. Accommodation, room size, etc.
average, but the air and heat always work well.
I have stayed in holiday inns since I was a kid. I really enjoy them and stay there unless I have too.
