Hi there
Yes there is a hairdryer in the bathroom and it works adequately so no need to take your own.
As for Baileys - i an only guess that they is some available as most drinks are, however, this will not be included in the all inclusive drinks and i have no idea whether the drinks that you have to pay for ae expensive compared to here.
You will need your own iron.
there is a clothes airer in the bathroom as they want to try and maintain the appearance of the hotel by not having too many items hangin off the balconies. however. your clothes won't dry as quickly so you can still put them out on the balcony table and chairs.
Also any men in your party need not be too concerned about the dress criteria. even though they state that men should wear long trousers and ladies cannot wear shorts, they did not enforce this rule. it would have been better if they had as i think it is nice to dress up for dinner.
all in all i cannot say how much you will enjoy being at this hotel. i am even considering returning next year
