Star Princess departing Copenhagen May 15th......looking for a few people to join a DenRus tour in St. Petersburg.....Peterhof, Catherine's Palace, Peter and Paul Fortress/Cathedral, St. Isaac's, Church on the Spilled Blood, Cruiser Aurora, The Hermitage, etc. Contact soon - time of essence.
did you put yourself on Denrus calendar showing you're available? i found our party there leaving on May 25th.
if you can't get a group together, Denrus has a smaller standard group excursion you could join for $265 per person for two days. they have early entrance to major sites to avoid waiting in long lines and are an American company fully insured and accept credit cards so I felt safe with them. the have a usa phone number on their web site. denrus.ru call them.
let me know how things go for you. i'll post here when we return as well.
