To better visualize the positions of the two hotels I attach a Google Maps view (the second pink dot is the "old" HGI Milan Malpensa, now Dolce by Windham.








The "old" Hilton Garden Inn Milan Malpensa, now Dolce by Wyndham, which until 2008 was known as the Grand Hotel Malpensa, before the rebranding as a Hilton Garden Inn.



The old Grand Hotel Milan Malpensa, in the past known also as Domina Inn Malpensa, before the renovation works and the rebranding as the "new" Hilton Garden Inn MIlan Malpensa.


In this enlarged image from Google Street View the hotel is still showing the old name SHG Grand Hotel Milan Malpensa, a name which however should not be confused with the almost similar "Grand Hotel Malpensa" (without Milan) which was the name that until 2008 the other hotel had (that is to say the "old" HGI now rebranded as Dolce by Wyndham).
