I have checked HOTWIRE. It only gives me 2 hotels (4 and 5 star) in Mayfair-Soho area, Chelsea-Knightsbridges area, and The City-Tower Bridge area. The 5 Star hotel is for $330/night, which is above my budget. In addition, I have checked the Hilton website, and I can get the Hilton on Park Lane for $240, or the Hilton Tower Bridge for $270 (advanced purchase rate). I have checked with both hotels, although they will not offer rooms online for 3 occupants (including the infant), they have no problem having an infant on board, and asked me to add it as a note on the reservation. The 4 Star hotel with the following amenities for $130 Fitness Center, Restaurant(s), Business Center, High-Speed Internet Access. I am thinking that it's a little too early, but I'm leaning towards trying bidding on priceline, with a target price of $150 - $180 for a 5 star hotel in Mayfair-Soho area. I appreciate your help.
