After reading this thread plus several others on the Conrad and Hiltons, my impression is that:
- Hilton Brussels City is easiest to get to/from airport or anywhere else by train
- Hilton Brussels has an executive lounge but it is often overcrowded, any anyway won't be Hilton past Feb 1
- Conrad is perhaps nicest but also more inconvenient to/from airport.

I need to be in Antwerp (actually Wilrijk but uses Antwerp station) next week and again in late February. It might be easier to stay at the Brussels City, so it's one train from airport to hotel, then one train plus cab next day to and from Wilrijk, then one train back to airport following day. Or maybe it's easier to stay in Antwerp, do two trains to/from airport, and only taxi to/from Wilrijk?

I can't find any good rates at the Antwerp Hilton (waited too long) and the Conrad and Brussels Hilton are a little pricey (but less than Antwerp). I can still get an OK rate at the Conrad City, or I could use a Diamond force for an award at the Antwerp Hilton or Conrad Brussels, or if it was really worth it, pay for the Hilton Brussels. Suggestions, advice?
