"You'll receive:
Maximum rewards of 50,000 points (3 points per $1 USD) or 15,000 miles (1 mile per $1 USD) with one qualifying event
Points for each room night, regardless if you or your guest is paying for it
10 Elite Nights when you book 10+ guest rooms for at least one night
Instant Silver Elite status or Elite Night credit towards your next level up
Working with a colleague? You can split your earnings – up to 50,000 points – if you’re both Rewards members."
(the 50k are on top of room-based points)
so, say, for a wedding with 100 people staying in 50 rooms, you'd get
- points for 50 room-nights
- 50k bonus points as long as the event costs 16.7k+ (which, with 50 rooms and wedding planning, it might?)
- 10 Elite night bonus
Not sure on the CC spend, but you SHOULD get the 5p/$ on your entire spend - don't quote me on this though
You'll get points for all the rooms booked, but you'll (pretty sure) only get elite-qualifying nights for up to 2 (or 3? I don't remember what the maximum of consecutive rooms-stay-credit is)
