I tought about taking a tour with them. Did anybody went already on one and could tell me how it was?
Thanks

I've never traveled with them, but I've seen their bus and I can assure you that if you like funky, you will love the Green Tortoise.

I haven't, but I did look into them and their hostel in San Francisco last summer. Do a search on this site, as I think someone posted last year about their great trip with GT.

I've traveled with them several times. Expect a younger crowd (ages 18-50) but all ages are welcome. Don't expect a shower every night and nearly half the bus with be foreigners. Most people are college educated. The trips are fun and enjoyable but if you need "Your Space" it may not be the right trip for you.

You should get a lot of advice on Green Tortoise if you post your question on the Thorntree...the Lonely Planet travel forum.
