I am a first timer planning my little eurotrip this summer break. Unfortunately due to budget issues I am only able to stay 20 something days… I have originally planned for July 22nd ticket from NYC to London, and have found a ticket for $540… But I can’t decide cause I’m secretly hoping that the prices will drop or something similar…. Should I book it now or later? And will I be able to cover air travel, transportation and every other expenses for 24 days with 3000 dollars? I am confused!!!
