IOS is a truly magnificent ship to look at.  The facilities on board are also great. Had a nice 14 night stay on board (albeit the last 2 days were really rocky on way back to Southampton), so holiday really ended on day 12, as we felt very sea sick.Now for the complaints.....  A few things really got my back up:Plastic plates and glasses in the self service restaurant - What is that all about?  We are adults paying thousands of pounds to stay on this ship!!!!Prices of beer and cocktails are over the top - why are RC so greedy?Room steward only started making an effort with fancy towels etc on Day 8 (prob building up to his tip).  When on Fred Olsen last year, we had fancy towels every day and a choc on our pillow each night (along with a plate of canapes every evening delivered to our room).RC guidelines for tips was outrageous.  They suggested nearly £160 per cabin (and we had 4).Now for the nail in the coffin ...We were a party of 8 (paid full price for the 2 kids as there were no family cabins).  We were allocated 6.30pm dining in main rest which was of no use to us whatsoever as no-one wants to eat that early on hols. We kindly asked the Maitre De on day one if we could change and he said he would check.  After 6 days we heard nothing and only used the main restaurant once.  My sister phoned him and asked if he managed to get us a few nights on the later sitting.  He left a message shortly after saying yes and giving new table number.  However he then called back and said, actually no, there was too many of us.  All in all, we only ate in the main restaurant 3 times because of the early sitting.  On the last night of the cruise my sister was clearing the messages and on listening to his message again, we were absolutely astounded to hear him swear at the end of the message.  He called us "f...king b....tards".  My sister promptly contacted guest relations who also listened to the message and were totally appalled by what they heard.  To their credit, they did pay $400 dollars towards my sisters room bill.  Overall, a nice cruise but nowhere near as personal and classy as Fred Olsen (albeit their ships are smaller).
