The suites are nice. Your guesstimate that they are about the size of a land hotel room is pretty close. For your extra money, your get a larger balcony, a dressing area and a bathroom with a spa tub instead of the standard "mini" shower stall. They also have a mini bar. Then like stated earlier you get priority embarkation (meaning you don't have to stand in line, you go through a seperate check-in proceedure and then on to the ship)
So, you can decide for yourself if its worth the extra $$. It truly depends on how much time you plan on being in the cabin. My typical answer to this question is, that since you are normally in the cabin only to sleep, shower and change clothes.. is it worth the extra money? For some it is. we have not done the suite thing yet as we have been bringing our childern along and the extra cost of them makes it a hard price to swallow. If we ever cruise with just the two of us, we may try it.
If you are the type planning on spending a lot of time on the balcony, then it may be worth it.
