Hi John
I'm not going on this tour because I'm already here (I'm a born and bred 'Jersey Bean'!), however, I've had a look at the brochure and think this looks like a lovely trip. For starters you'll be staying in a very nice hotel, right on the St Helier Waterfront area which is always beautifully lit around the festive period and also with super views over the marina, the bay and Elizabeth Castle. It's also only a 5-10 minute walk into the main shopping precinct.
Unfortunately, the dates of the tour mean that you will miss our annual Christmas festival 'Le Fete De Noue' (markets, entertainment and a grand parade) which is held over 10 days in early December. However, there is always plenty going on at this time of year, including two local pantomimes if you are that way inclined.
The one thing to bear in mind about our little Island, being on the edge of the Atlantic Ocean, is that in mid winter it can get quite damp and misty (and frequently extremely windy!). We also have lovely wintery blue sky days too, but be prepared for everything. Providing you pack warm layers and a rainproof jacket, you will be all set
Happy to help with any other 'Bean tips' or questions that you may have.
All the best
Mandy
