We've cruised on the Regent Navigator and Mariner several times, and are considering booking a 6/2/13 London to Iceland cruise on the Regent 7 Seas Voyager, a 5/16/13 Silver Whisper British Isles cruise, or an 8/4/13 British Isles cruise on the Silver Cloud. In order to make a decent cost and value comparison, we need to know what is and isn't included on Silversea. We'd appreciate your comments. In most cases, we'll indicate what's included on Regent, and hope that fellow LCT people can tell us what's included on Silversea:

Air. Seems to be included on both. Business class upgrades are usually $999 each way on Regent.

Pre-cruise hotel, with transfers - included on Regent, or you can get a $300 per person fare reduction.

Tips - included on Regent.

Wine, beer, and most booze - included on Regent.

Excursions - included on Regent, but many are pretty lame.

Smoking - not allowed on staterooms or balconies on Regent, and allowed in only a few public places.

Washing machines - available and free on Regent.

Bottled soft drinks - free on Regent.

Shipboard credit toward what's not included - nothing on Regent, appears to be $1,500 per suite on Silversea.

Feel free to give comparisons other than cost.
