can anyone recommend online discount airfare sites....i have checked out easyjet but was hoping to compare prices...my daughter and I are arriving in london on the 6th of september to spend a day or two before we go to madrid for the year....the fare directly to madrid was twice the fare to london... now i must find a fare from london to madrid....does 50.pounds for a one-way sound about right...i am thrilled to be able to explore the city ...any recommendations for kid friendly spots... i dont plan on doing the expected sites but rather a lot of walking to get a feel for the city... any recommended parks...coffee shops ...restaurants (indian, jamaican, etc.)....kid friendly cultural events/attractions...is it possible to rent a stroller ...my daughter is 4 1/2 and her legs tire long before mine....also, can anyone recommend a hostel.....thanks for any thoughts and suggestions
