Couple with teenage daughter looking to share private tour guides for St. Petersburg on July 5 or 6. Sailing on Noordam. Might do HAL excursion on 07/05 to Hermitage because museum is closed Monday to most visitors but is open for HAL excursion. Could book tour on 07/06 with Red October or DenRus. Have proposal from Red October for 2 days but I'm sure they can be flexible this far in advance. Please indicate if interested. The larger the group, the cheaper the per person price. Looking for 3 or 4 more travelers.
