I always enjoy reading people's perspectives and take the points into consideration.
FWIW, I prefer the T5 as an actual hotel...I'm always treated well and it's one of the few hotels where I have had 100% upgrade success rate.
The one obvious minus is the location, but it still works for me when I have T5 flights...
Unfortunately, I have a regular flight that used to be T5, but now in T3...As such, I moved my stays for those flights to the T4 location.
Whilst the location is better, I don't like the rooms as much and there's just something lacking for me. Having said that, I do enjoy stretching
my legs and walking to the terminal when time permits.
