I dont know the details on where they are training specifically but from what I have seen of HS and college sports in america, they have better facilities than a lot of pro sports in the UK to be fair.
It sounds like they are training twice a day and in between that, they will have the plunge pools/ice baths all ready for them I am sure. All in all, I am happy for them to go over there for the bonding alone and I think the Australia trip later in the year will be a good opportunity to take stock of where we are up to and work on fixing a few issues,
