We're thinking of taking DS to WDW next May for his first trip - he'll be 16 months old. We are also probably going to take my Mom with us. She'll pay for 1/2 the room and be a big help with DS. My SIL is a WDW freak and I am so afraid that she'll try to tag along with us. She already mentioned something to my DH about it. She tried to tag along on our cruise 2 years ago and DH discouraged her. She tried to tag along on our trip to the mountains last fall - AND bring her very annoying friend with her - but somehow DH and MIL talked her out of it. She successfully tagged along on our Vegas trip last year and while that went okay I dont want her to come to WDW with us for several reasons. The first is that she thinks she is a WDW expert - but I have been way more than she has. I know if she went that we'd have different ideas about how to do things. Also, I think for DS's first trip a small group is best - the more people you add the more problems you have trying to get to places. AND I just really dont want her to come. Any ideas on how to discourage her? It may be a lot harder when she finds out my Mom is coming.
