We're on the 7/29 from Baltimore. We booked back in November when we first heard. According to our ta she had to make the rounds at Celebrity to get us the $100 shipboard credits because the price is now considerably higher. I don't know the current price, but our booking is a very good value for an 11-day cruise. However we booked two connecting inside cabins for our family of four, the extra space (and bathroom) was worth more than a balcony to us.
Good luck whatever your choice.
