Just saw you can book rooms in May and June at Prague Marriott for 80Euro per night tax inclusive. That's a pretty good deal.
Where did you see this deal?
I made the reservations this morning, and when I just went back to look again the price has been raised about 20 Euros per night. Still not bad, but not quite as great of a deal. The Hotel K+K Central has also quoted me 100 Euro per night, the Ventana currently has a promotion on www.utell.com for STAY 4 PAY FOR 3 nights, and the Hotel Josef has offered me 117 Euro for a Superior Deluxe with Balcony and Castle View. I think the high end hotels are softening a bit.
