Congratulations to you! I can't beat that, but I can scrape the bottom of the SPG barrel in part:
Proposal at Le Meridien Rio de Janeiro (now sadly departed)
Second night of married life at the Sheraton Heathrow
Honeymoon was not SPG based for us back then.
My wife still doesn't let me forget that our second married night after leaving the wedding venue was at the Sheraton Heathrow. What a way to kick off a honeymoon trip. They had even changed our booking to a twin room, which took about 15 minutes to get them to change back. 8 years later, we still end up staying there to be consistently disappointed. Like marriage really
May the pair of you enjoy many happy years of married life and travels ^
