Any drawbacks to a cabin on the port side of the main deck?
Dan is still making bubbles, I guess, so I will attempt to answer.
I was on the Ferox last July. As best as I can recall, there are just two cabins on the main deck - both singles. The rest are all below deck.
So if you are referring to one of those two singles, and more specifically, the port side one, as I see it, the biggest drawback is that it is right across the kitchen so it gets noisy really early in the morning. Other than that, both of those are a bit smallish compared to all other cabins.
I prefer either of the two singles just below those two, but they are below deck and you have to climb up and down a ladder (not a staircase). They are larger, albeit a bit more money. They still get a bit of kitchen noise but not as much.
And while I am at it, I might as well give you my two cents' worth on the remaining cabins, which are forward and also below deck. Those are nice and spacious and possibly less noisy....BUT......the door on the main deck that leads to those cabins is on the port side and when it is a bit rough during the crossings (and on my trip, at least going out was) you may get drenched by the splash from incoming waves as you come in and out. It was also probably not a coincidence that on my trip, the people who were in those cabins were the ones who were hardly seen during the crossing to the island during meals....a lot of them were seasick.
