Hi Sparky,
We did the Destiny last Jul 08. Had a ball. Enjoyed it that much we are doing a 2 week back to back on the Destiny, 30th Jul 09. Fantastic.
Seven Seas - Dressy Occasion for evening meal - The Captains Night - Lots of gents wearing Tux's and ladies wearing Frocks. I always wore Trousers and Shirt and on Captains Night stuck a Tie on. Wife always wore nice skirts and tops etc etc. Daughter wore much the same. So not too over dressy. Although no Jeans at night in Seven Seas.
Seven Seas - Do a great Breakfast and lunch - You can wear your shorts for these 2 sittings
Lido Restaurant - Open 24 hrs. You can wear what you want. Great curry and chip at 3am on the way back from the pub to the cabin. lol
Grill Bar - Up beside the pool. Open 10am to 5pm ish. Wear what you want.
Not sure about the destinations. As Kimi said you would be best to email Thompson to varify destinations. Cant even remember my destinations. But whatever port I wake up to, im sure ill enjoy it anyway.
Have fun
Colin Northern Ireland
