Been trying to get a night (1/5-2/5) at a 4* Hotel in the London City area, particularly Westminster, Mayfair, Marble Arch, London City/Tower Bridge areas, but can't seem to get it. Bidding $130 and up, went to $152 and still nothing. Is it advisable to wait till I'm closer to May to book (like say, 3rd week of April), or are prices for this time normally unusually high? Any help is appreciated! (And yes I've been using site PRICELINE links to search and bid). Budget's around 155 tops excl taxes.
