Just jumping in, pardon, but I know Linetbo read my trip report from the Baltic last year,
http://torussiawithmickeybars.blogspot.co.uk/ now firstly we have used Anastasia twice in 2010 and 2015 both for two full days and one evening. They are fantastic. You will see more, do more, have a great price and the CEO Anastsia does take personal interest, she met us in the port on disembarkation, and embarkation and also in the tour st places. We had a full day the first day from 8 am, ( scheduled arrival time was 9 am but we got in early, ) we stayed out the first night getting back at 9.45 pm.
We did the riverboat, we had one for our family it was great, brilliant shots, and it was cheap. Now for
DCL tours if your out day and night, you will have to go back to the ship, go through immigration, meet back up then get back off. Travel time to/ from the city us another thirty minutes each way, we stayed out! We Also we the the Faberge mesuem, and a local meal, Anastsia can organise what you wish, also a night a the threate depending what time it starts, ends and ship departure time. Basically you normally email Katherine, she will do what you ask, when I emailed for a helicopter, she said yes, first one was expensive, do she found be another that's cheaper. So ask what you want, we did a lot that evening, in fact our brilliant guide is still exhausted as I personally overworked her, we went to Yousof palace where Rasputin, was, and not normally served on DCL tours.
I recall a DCL trip report in 2015 saying, " we spent 11 hours looking at the inside if a bus, we'll do not let that be you, book a private tour everyone gets a window seat and a personal guide, just look at my trip blog, do much on it, including the helicopter video links. Yes our hour long river cruise was fantastic, just my family on it, not 55 looking for outside seats, we had the bost to ourselves, it was fantastic.
The DCL tour times make it hard to do a day and a night tour, you may get thirty minutes on ship to have a snack, if you do a half day morning and then an evening it nay work, but do nit loose time, just have a day and evening out in one tour with Anastsia. Some will say you need a visa, no, Anastsia sort that out fir you, on your tickets there your border pass.
This is a wonderful city, and you want to do it justice and the very best way, concierge service but at affordable prices. I do not get any commission, not connected with them, just want you to have the best time there. A high number of DCL cruisers in 2015 and 2010 did what I recommended thry all loved it, and felt it was the jewel in the crown. Example at the hermitage, we went in a side entrance an a runner hit our tickets, no waiting like cattle outside in herded groups. If it was busy inside, we went a different route to the tour groups.
Anyway if you go say Hello to Katherine and Anastsia for me!
