Can anyone advise if this hotel is able to provide, with no additional, late departures after the seaplane cut-off hours?

For evening flights in MLE the Westin provides the alternative of a speedboat transfer to the nearest airport to catch a domestic commercial flight back to MLE.

This is extremely convenient if one has a 10pm departure from MLE.

Also, for all the knowlledgeable out there: is this property that much better than the Westin? I have a USD 250.00(+tax and fees)/day BRG rate at the Westin. Is the St Regis really worth throwing that away and spend north of 400k points to stay there?
