Is there elevator in Beijing Sanyuanqiao Subway Station and how to get to Wanda Sofitel Beijing from Sanyuanqiao station?

Hi! We would be arriving in Beijing around 12:00pm on May 16 and staying at Wanda Sofitel Beijing. Since our airline is at T2 we plan to take the airport express towards Sanyuanqiao Station. Then transfer to Line 10 towards Guomao Station. Get off and transfer again to Line 1 towards Dawanglu Station. Get off and finally taking the taxi to the hotel. We are 2 adults and 2 kids with 2 pieces medium-sized luggage and 1 small luggage. I read in some of your replies that there is no elevator in Sanyuanqiao Station to go to Line 10. Is there an escalator or is it just stairs? Please give me the direction from Sanyuanqiao Station to go to the Line 10 Station?

Do you recommend taking the taxi at Sanyuanqiao to go to the hotel? How much will it be and how long will it take. My concern is the traffic jam to get to the hotel if by taxi. Any reply would be greatly appreciated. Thanks!
Sincerely,
Olivia
