We're staying in Chantel in 1800 at Easter @Elsie42 We skied past it last year and I told DH that that's where we were staying next time so that we could ski to ski school and not have to walk up that flipping hill next to the Transarc to get to the ski school meet point by the Dahu lift.
@Larsson11 Stay in 1800 if you've got complete beginners, then. It's got a really long green that they start on, the Mille 8 run. It's a fun park, so there's xylophones and arches etc.
We've bought an interrail pass as that worked out the best value. You just need to book seat reservations for your chosen trains, then. It has been really simple, though due to the time we're due to arrive in Bourg, we'll get a taxi to the resort. This is my fault for not reserving our seats on an earlier train from Paris before the interrail quota of them had sold out.
Trains are getting booked up, so I'd do it sooner rather than later. What dates are you going?
You will need a lift pass, yes. Go for the Classic pass (the cheapest one). With complete beginners you won't use the Essential (access to La Plagne included in that one).
We're hiring from Précision Ski in Chantel as its at our accommodation. We booked through Alpin Resorts, and they have constant offers with a promo code. The current code is PROMOTIX. https://www.alpinresorts.com/en/ski-rental
If you stay in 1800, Evolution 2 are under the Arc Adventures umbrella from this year. We've booked with them.
