Just thought I'd let everyone know we had a great trip.
Stayed at five SPG hotels...
Sheraton Dusseldorf - at the airport. Great location, simple and small rooms. Nice staff. Good breakfast (tho not cheap). Directly above (same building) as S-Bahn for direct connection to the Dusseldorf Hbf, which was perfect for me.
Sheraton Milan - at the airport. New hotel. Very nice rooms for a Sheraton. Upgraded one of our rooms, but was thoughtful enough to put both rooms next to each other without a request.
Goldener Hirsch, Salzburg. Great staff. Wonderful location. Upgraded one of our rooms to suite (they only have four in hotel). This was a paid stay, tho with promotions and discounts was reasonable.
Westin Regina & Europa, Venice. Great location, tho not necessarily convenient for smaller family run restaurants. It's located right in tourist central. Fantastic bar on the canal (they make a wicked coffee and include pastries, cookies, and more for no additional charge). Upgraded both of our classic cash & points reservations to larger rooms (one of which was a several level upgrade to a huge room with a double sink, sitting area with couch and two chairs, more).
Westin Excelsior, Florence. Reserved speciality suite on the river. Got 2nd floor with excellent view, was able to watch fireworks during their patron saint holiday festival in June and the thousands of people on the street... Room and hotel is tired, showing the 14 years (or so) since the last renovation but still quite nice.
St Regis, Florence. Absolutely wonderful. Hotel opened three weeks prior to our arrival. Room was pristine. Service was impeccable.
Westin Excelsior, Rome. Reserved speciality upgrade, which was jr suite. A junior suite in this hotel is a 1-bed apartment sans kitchen. Huge. They upgraded one of our reservations to a full suite, which is doubly huge - bedroom had two armchairs and plenty of space, living room had enough furniture for 9 people with room to spare. Good, but indifferent, staff. Annoyed by their assurance taxi cost €45 to the airport, but they put us in a van that wasn't a taxi and the guy insisted on €75 after the fact...and since it was 4am we didn't even think of asking before leaving. Oh well, it's Italy.
All in all, great trip. Also spent three nights in Bellagio at a fantastic little hotel with a superb restaurant specializing in fish from Lake Como. If anyone needs details just send me a PM.
