First do you have any prefferences as it realtes to FF programs?
If not, it kind of depends which cabin your are travelling in. In economy go for SK, beats CO hands down any time. And the A330 is a far supperior aircraft to Economy Extra product (sometimes it is available for a cash upgrade of USD 250 at EWR) this is a great product. In business it is a bit more of question mark. At the end it of course depends on what the prices are for the dates you are travelling.
As it relates to hotel: As indicated above you need to supplya bit more information. If you want to go for a designer and something out of the ordinary try Fox Hotel - designed and used for the launch of the VW Fox car.
