Cabin with Obstructed view
 

I hope You'll are doing well. I just want to know that outside my cabin is observation deck. is it okay? or should i rebook?.

it would help to know what ship you’re talking about. If we could see a view that you’re talking about I think it would be more helpful.

Yes, tell us what ship so we can look up the deck plan.

Ship and cabin number also.

From other posts it looks like they are on Icon of the Seas.
Still need cabin number though.

Go to the deck plan for Icon of the Seas and click on the deck you are on.
They say if the cabins have obstructed views right on their website.

Thank you guys i have just changed the cabin successfully, It was lifeboat obstruction and it was teasing.

I would have done the same thing. In fact I did once when we had a cabin with a lifeboat obstruction. May as well be happy with your choice
