I am travelling to WDW with my 4 year old this fall. I have been many times, but this is his FIRST! He is enrolled in a pre-school several mornings a week and really craves playtime with other kids. I am considering his attending the Lion's Cub Den child car facility for an evening or two. I've reserved space, but can cancel. Looking for honest opinions of those who've used the Den for their pre-school aged ones. Thanks.
