I usually write an email to the hotel to notify them about our arrival time, ask some questions (e.g. pick up service, location, possible upgrades, ...)

Wow - I was impressed - and a first for me - only 5 minutes after I sent the mail I already received a reply from the guest service manager. - (I remember having to wait 3 days for a reply from the IC Paris Le Grand )

They offered a 65EUR limousine pickup service at the airport, but that sounds a bit expensive (as expected) for the short ride.

And moreover - they asked regarding upgrade if I was fine with a one bed room because I booked a classic twin bed room (travelling with my nephew). I said we would be happy to share a Kingsize bed but need to negotiate the blanket-sharing terms in advance - they replied "we will make sure that you will get separate blankets when you are assigned a King size bedroom
Never thought about requesting separate blankets for a king size bed ...
