Sometimes in the app the prices for points are cheaper than on the web, not always. I think the points purchase promotion is still going on, that is, with the 30% plus, each point costs approx. $4 so the night will cost you about $300, a big savings!
In case it doesn't work, it is still much better for you to buy the points and make the reservation with points.If the app says 72,000 points, it is correct. It has never failed me and on many occasions the reservation with points turned out better than paying

If you purchase the points, I would appreciate it if you could confirm if they have given you the 30% bonus because it's a good deal

As a Melia Platinum for life member, I asked directly with Melia Reward platinum costumer service about this promotion and after waiting a few minutes, they asked me where I got this promotion from, because they say it is an internal Melia link that is not active. I have told them that if it is not active, they should remove it because it confuses customers. So it seems the extra 30% doesn't work
