What I find amazing is not that the surcharges are rising, but the time periods between the implementation of the increases are so short.
The current charges for Celebrity are $8 pppd for the first two pax in a stateroom and $3 for third and fourth in the stateroom, according to this Celebrity press release
-- and that was effective May 1. The new charges of $10/$5 take effect less than 6 weeks later.
Also, the cap has risen from $112 per person per cruise to $140. (At least they have a cap -- NCL doesn't.)
Yes, the increase for Azamara is certainly a shocker.
Enough of this analysis... I'm getting a headache.
