Re Infants in PE
A few questions I know up stairs there is a “Wardrobe” where the larger carry on bags are stored, From a Virgin and the current Security point of view are we allowed to take on board an Infants Baby seat, i.e. the smaller ones with a handle, or would this have to be checked in.
Is there a similar wardrobe on the lower deck.
If it has to be checked in can it is checked in at the gate similar to a buggy, i.e. on our last day we will checking at Downtown Disney, but need the seat to get back to the airport,
Trust the above is clear, and once again thanks for your help.
