I’m planning on a short ski break and looking for a little help on others experiences of a couple of things.

Firstly is the Gatwick night before bag drop 100% reliable, or if using it should be check at the lounge or gate the next day our bags have been remembered?

Secondly any experiences of a sensible amount of time to leave between landing and a shared transfer at Geneva on a Saturday lunchtime in Feb? Bags will have priority tags FWIW (Also OT but any recommendations on best shared transfer to use appreciated). Thanks!
