Hi tricksykent
In answer to your questions, we stayed in the adult section last May and have booked to go next year.
All rooms in the adults section have optics but be prepared to only have a choice of two bottles of beer,coke,sprite fridge replenished every other day.
limited sun loungers in the adult section resulting in a free for all at the start of the day, 24 hour snacks are available in the main section of the hotel...includes burgers, drinks hot dogs and salads.
Room service was not available during our stay which was only a few weeks after opening.
Thomson aircraft is a Boeing 757-200 with winglets.
Having said all that it was a great holiday....Enjoy
