彼得戈夫有不少景观,主要是Lower Park。Lower Park 9:00-20:00中间没有时间限制,我文中提到Grand Palace是有时间限制的。我正好在你提供的链接中打开的问答部分,内容中明确5月到9月该网站上不支持在线购票。具体如下:5. Why tickets to the Grand Peterhof Palace are not available on the website?Because of the large flow of tourists in the summer season pre-sale of tickets to the GrandPeterhof Palace is not available. Entrance tickets to the Grand Peterhof Palace can only bepurchased on the day of your visit at this museum's ticket offices from 12:00 to 14:00 and from16:15 to 17:45 every day except Monday and the last Tuesday of each month.From October through to April, tickets to the Grand Peterhof Palace and other museums of thePeterhof State Museum-Reserve will be available on our official website.http://tickets.peterhofmuseum.ru/docs/en-faq.pdf?2076如果要进入Grand Palace,你最好提早去排队,我们用了一个半小时才进入售票处。还要遵守它们的时间限制。最好抓住一个可以跟你交流的俄罗斯人,以防万一。祝你好运,我在圣彼得堡买回的一本书中有些照片,还是值得一去的。
