Hi I have been trying PRICELINE to travel to Berlin in early Sept for a week. First, I tried with 45 for 5 star and increase to 55 and later add 4 star, down to 45 add zones increase to 50. Nowadays I tried up to 61 because PRICELINE offers to me for 61 (4 star), when i tried, it didn't allow me. Anyone pls advise? thx
