I have to say that my curiousity was peaked when I saw this thread as I have been toying with the idea of inviting DD's bff on our trip next fall. I fully intended to pay for everything except air and park tickets (which would run her family about $350.00). Since I can't afford to pay for an extra child I may want to re-think this idea! However, I did plan to pay hotel, meals, souveniers (the kids will be 5), etc. Now I am not sure if I should do this as I pride myself on using correct social etiquette! Any thoughts?
