The main building is RPC club level. The price difference will be $$$.
Do you want/need cl?
I have stayed in the outer buildings and its lovely. I would choose BPK for a view of poly and convenience to both pools.
Last summer dh and I ended up in boca chica and loved it. We did dinner one night at Narcoossees and to walk and not not worry about transport was nice,
Mind you my next stay is RPC. We only have 2 nights and 3 adults so I wanted the extra space offered in the lounge. Also we won't be doing much in the parks and will spend a lot of time at the resort so it made sense to have cl this time.
Not as magical? It's the GRAND

it will be magical whatever category you choose
