2. Extra point earning promotions 2x, 3x, 4x point earning or a set point bonus.

No reason to horde points to increase point value. There can however be a disincentive for redeeming points when there is a decent point earning promotion running. Point earning promotions usually have this condition "Any stay partly or entirely paid with Le Club AccorHotels Rewards points will not be eligible to receive this offer" in the small print. eg redeem a single 2000 point block against say a 3000 CAD$ reservation which would be eligible for 4x point promotion cancels the entire promotion point bonus so you only earn the normal non promotion points. Accor on occasion forget to enforce their own T & C's but if they do using points in the wrong circumstances can be costly.
