Hi Janet,
The three TS tours I've done are: Chile, Argentina and Brazil (before JY started offering this tour), Tales of the Balkan Peninsula and the Grand Baltic trip. On each I was not left to eat alone! On the CAB tour, I went with a friend so that was a bit different; however it was a small group of 14 and two of the couples were very friendly and we ate with them on several evenings. On the Balkan tour, most dinners were included and I was befriended by a lovely Welsh couple and sat with them at most meals. On the Baltic tour, I didn't find the couples so friendly but there were two other single travellers and we got on well and generally ate together. I'm doing the Canadian Rockies in Sept with TS and am travelling with two friends. Together we make up the three solo travellers on that tour and so that will be grand!
My views on going with TS (and I've also travelled with Jules Verne) as a single are that I don't mind going by myself although I do try to get at least another travel buddy to go with me. I would check the itinerary to see how many dinners are included and for any nights that do not include a meal, I'd check the hotel website to see if the hotel had a restaurant, or if there was one nearby. If I was travelling by myself I'd keep my eyes peeled to see if there were any other singles or others who may welcome some company, but if not I'd be prepared to eat by myself - and bring a book or smart phone for company! I've found that some of the couples usually eat in the hotel as well and if they are friendly, may extend an invitation to join them.
So far I've been fine on TS tours - and also have to say that on some JY tours where dinner hasn't been included I've ended up eating by myself on occasion! It wasn't the end of the world, although I'd obviously prefer company. (On some JY tours I've been eating with the group and wishing I was eating by myself, but that's another story!!!) JY are now emphasising that the tour manager will help customers to find somewhere to eat on evenings that don't have a group meal - previously that was NOT the case and some TMs did make an effort, while many did not. I presume that seeing as the company use the same TMs on JY and TS tours, that the tour manager should be prepared to help a single travellers find somewhere to eat on a TS tour. Vickie and others have recently stated that customers are welcome to join the TM for dinner - I haven't seen this in action yet and I would think that, based on experience, some TMs wouldn't be keen on this - but if it is now company policy, then they would have to oblige!
Any other questions, I'd be happy to help. At the end of the day, if it was a tour I really wanted to do, I would do it, with or without travel buddies, whether it was with a single traveller company or not.
All the best,
Bob
