My family is planning on taking a trip to Europe to celebrate our daughter's (only child) Middle School graduation. Her first trip to Europe was over Thanksgiving last year, and we visited London and Paris. She absolutely fell in love with London, and wishes to go back on this trip. We are going in February or April of 2014, during her school vacation, to hopefully cut the cost down. Anyways we are aiming to start the trip in London. Any suggestions of places to visit that are a reasonable distance and can be reached my train (preferred not necessary)? Thanks!
