I will be at Universal without my husband and my 7 year old can't handle several of the rides. (Several rides - can't even do Spider-Man or Gringotts). Do you think TM's would question me using child swap and have my eldest child swap off with me? He's 13 but can easily pass for 15. (I have read they have to be 14 to be in the parks without an adult so hoping he looks old enough that they will let us use child swap without question).
