^^Sis, I have tried Globus (sister company of Cosmos) in one of my European tours (it was a "European Sampler" tour - visiting France, Switzerland, Germany, Amsterdam, Austria, Vatican and Italy) and they have very good service plus the tour guide was really good. I really learned a lot from what he says of every place we visited.
The restaurants included in the package were good and authentic, so no complaints. The hotels we stayed at are not the 5-star ones but very quaint boutique hotels which I prefer as they are so charming.
Actually, the Globus itinerary was explicit and walang daya so to speak. If they put in a 16-day Mediterranean tour, you really get a whole 16 day tour. I guess that's what you call professionalism and of course, they have been in that business for ages na.
The only problem i have with coach tours is that you literally do not unpack anymore, coz you leave so early the next day and that you have to load/unload your luggage at every country or hotel stop, so medyo stressful ... but generally, it was a very good experience for me. My husband and I have made lasting friendships with some of our tour group (of different nationalities) -- nice to have friends from all over.
I also like the fact that you don't have to think of anything anymore, from looking for a restaurant, to lining up for entrance tickets to tourist attractions. Everything has been pre-done for you.
If you prefer to join a group na all-pinoy, then I guess you can opt for a locally-arranged tour group, but if you are "game" to meet people from various countries (pero madami din na pinoy sa international tour groups ha), then why not try an international tour group. You can also do a DIY tour as what our sis suggested here, just research very well so you don't miss out on the "must-sees" and the "must-do".
I have friends and relatives who have tried Cosmos, Trafalgar and Insight --- all good reviews too!
I got to tour around Mediterranean (+Turkey) and Scandinavia (+Russia) too but this time I joined a cruise to both regions. Now, that's another superb way to tour Europe!
