Incredibly easy - so far the customer service from this company has been fantastic. Although I have only spoken to two members of  staff, if they are anything to go by, this company operates in a totally customer focused and friendly and flexible way. Should I mention names? OK, I will, Lora - always replies to emails, always willing to help (we're a group booking so all the individual arrangements and queries are quite a test!). Just the training to do now...and hopefully positive stuff to feedback about sportstours as the event gets closer and takes place
