We were on the June 4 cruise out of Southampton to the Canaries and I totally agree with Pandemonium.
The price of the drinks package was utterly ridiculous. The cocktails and other drinks were all overpriced and looked cheap - seriously only a quarter of a slice of lemon! I know it's petty to mention that but it goes to show the level of penny pinching involved.
The sun bed situation - yes agree again although I personally sometimes prefer to sit in the shade. The promenade deck on other ships has always been a good place to sit for a different view and some peace, but on Anthem you can't do a complete loop and there was no seating available.
As to the tips, my husband got severe diarrhoea on this cruise and I understand he wasn't the only one. He was stuck in the cabin for three days and missed 2 ports of call - based on that maybe housekeeping earnt their money!
