I've used it for 3 journeys now... A return to Disney land Paris and a single from Paris to London.

Have been in premier and standard, and to be honest the standard is literally the same as Premier just without the free food and drink. Same seating or very similar if there is a difference I couldn't work it out. Just not as many customers in Premier than standard.

Quite reasonably priced if you can book in advance. And obviously ideal for Disneyland Paris. The station really is in the Theme Park Entrance.
