Sim and I have been to Malta twice this year. The first time we stayed at the Hilton for 3 or 4 days and decided to stay longer on the island, so went for the Westin (big mistake!). And we went again earlier this month, origionally for 3 days and ended up staying for 7, all at the Hilton.
I love the Hilton, wouldn't stay at the Westin again and wouldn't go to the capital again (even on a day trip).
I can see why people don't like the place. But if you travel alot and you just want to realx for a few days, have some decent food (the Thai restaurant in the Hilton is good as is the more expensive restaurant in the Westin complex) and loose a few dollars in the casino in the evening - Malta is fine.
