We are planning to take DS who is 7 years old and DD who is 20 months old to Disneyland Paris this year in either May or October half term. We've ruled out summer as I've been told its the busiest time. I assume May will be quieter with better weather but is the Halloween theme in October worth the extra queues and potential rubbish weather?? I'm also not sure if waiting until later in the year will be better for DD as she will be slightly older or will 5 months not make any noticeable difference. October also looks to be slightly cheaper. Any advice would be greatly appreciated please as I can't decide what best!!
