yes, I'm getting married at the Princess! when is your wedding?
So the Grand Sunset Princess and the Grand Riviera Princess are essentially mirrors of each other. They each have their own lobby to check into and have restaurants on both grounds but you essentially have access to the same pool, amenities, each has their own buffet but you can go to either one.
The Princess also just opened their new Adults only hotel right beside these two complexes. It's called the Platinum Yucatan Princess Adults Only hotel. As of September 1st, 2014 the Princess opened up their adults only hotel, allowing guests of the adults only to cross over to the GSP or GRP. Guests of the GSP & GRP cannot cross over to the Adults only though. The GSP and GRP now specialize as a family hotel and have focused more of their branding towards catering to children and families.
I have heard nothing but great things about the new hotel. I think that the Princess hotels have an amazing price point and are a bit of a hidden gem. We have stayed at the Grand Riviera Princess twice and loved it. The Grand Riviera had the Adults only platinum block of rooms prior to sepof 2014, where as at the time the Grand Sunset Princess didn't, so I think one was trying to cater to adults and the sunset more to families. It's a little confusing but essentially they are all connected...except the new adults only which is next door and is only accessible if you are staying there.
Our guests are staying at the ADults only with the exception of two families that are bring their kids. They are staying at the Sunset. Our ceremony takes place at the Grand Riviera and the reception at the GRand sunset chill out...it sounds spread out but it's all together.
I would suggest you fight for the perks before you give up on Azul Fives. Stand your ground and tell them that the bottom line is that you either get what you were promised or you are taking ALL YOUR guests with you to the hotel next door. Don't back down.
The princess hotel is in between the Grand Velas hotel and the Azul Fives. Azul Fives is just south of the Princess.
