Hi, dY’quem
Im not being sarky, but really, really, the Marriott Regents Park is not, and never will be comparable to the Wellesley. Marriott does have the five-star Park Lane property or the JW that *might* reach Wellesley standards, but your review is a great demonstration of the reason Marriott took over Starwood, it was short on top-end properties and the ordinary Marriott hotels are not top end, nor do they pretend to be.
Ive stayed several times at this property and would mark it as thoroughly representative of the Marriott full service brand, and that includes long waits for the phone to be answered and keying mistakes to the Exec lounge! As for tea being delivered to the room, I didn’t know Marriott offered it at all. There’s a kettle in the room for that!
