Alaska;Why is Spirit more $ than Celebrity?

[GOTTA CRUISE NOW]

Looking into booking Alaska cruise for next May. Why is Carnival Spirit a few hundred $ more than Celebrity and Royal Caribbean?

 

I've always been loyal to Carnival, but they're making it difficult! I love the Spirit, or any Spirit class ships, for that matter! BUT... I'm thinking of switching for this one.

 

Please give me your input, my friends......

Don't know which itinerary you're looking at, GCN, but could be because of port times. (?)

 

Generally, it seems that the Spirit has preferable port times almost across the board. That was one of the primary reasons I chose the Spirit over other ships. That and the wrap-around aft balcony I was able to book!
