My KLM flight from London to AMS (and eventually MSP) will leave at 6:30 am from LHR, so I wanted to book my last night at the airport. I've searched through many posts here, but that's when I thought I was flying out of Terminal 3. I checked my ticket (duh, what a good idea!) and realized it's Terminal 4, not 3. The flight is not until April of next year, but I like to figure out stuff like this ahead of time.
FWIW, I do not mind walking a bit - I have a lightweight spinner and will have a personal bag sitting on top, so it's not a problem to walk a half mile or a little more. But I do realize it will be dark out at 4:30 am, so I suppose it would be better to be closer. I do not want to pay for an expensive room, and would prefer something in the range of a Premier Inn or Holiday Inn Exp, etc. I saw that there is a PI near Terminal 4 but then I saw a post telling the OP not to book anything on Bath Rd. So I'm a little confused and would appreciate any help you can give me.
