Bliss units are basically a modernization of the Mayan Palace and the Grand Bliss is a modernization from the Grand Mayan - basically the same size as their counterparts but newer furnishings.The biggest difference is the G bliss has a usable balcony, larger rooms, and more luxury baths.

Bliss vs Mayan Palace - same square footage - different style interior .
Vidanta does updates to Mayan Palace interiors as well - so this is not about age of the actual furnishings in your unit .
Currently Bliss is only in RM . Vidanta sold enough contracts that they had to build one . There remains
talk / sales rumours that NV will have a Bliss at some point for the same reason .
Grand Bliss are in RM and NV . There is a GB model as of 2017 at the PV-Marina location that is currently Mayan Palace only (about 200 units ) . When built - it will be on the marina side of the property
In the last few years - one product Vidanta has been selling groups brand /buildings . ( This helps reservations management as well.)
