Has the bruising started to subside yet? Arnica will really help with that if not. Also if it is still swollen allow at least a week for it to go down and even then it could well swell up readily if you over do it. Agree with SL - the more you rest the quicker you heal.
You'll probably feel more comfortable wearing elastic bandage for a couple of weeks yet as once the joint becomes more mobile again it could still feel a bit stiff and awkward to weight bear.
What sort of holiday is it ? Can you take a book and sit whilst dd plays or is it more active ?
