I want to have a website that make travel plan from any City/Town to any City/Town. The planning could have preferences of price, time , distance or other filters. Travel can include all modes of travel like Air, Bus, Rail, Cabs(registered city cab). User can plan its travel but booking can be done after login. it should also offer Hotels of all stop of travel including both start and end. There must be ads to make some revenue but it should not distract user to its process and also there should not be alot of ads that user will find it difficult to search for useful content.
