It’s possible to transfer points between Marriott and SPG accounts without merge both accounts?
Or can I simply make reservation for Marriott hotel for points on SPG site?
You can transter points to your Marriott account from SPG during the combining of your accounts into a single account. The website is still glitchy with many SPG transactions not working properly for some reason. So if you want to make a reservation for a Marriott property with SPG points, you probably are safer to call Reservations/Customer Service for assistance. You can find additional information about this at Status.Marriott.Com
