Taxi from Chunhuiyuan Hot Springs Hotel/Resort to Beijing sights (Forbidden City & Summer Palace)

We are staying at the Chunhuiyuan hot spring resort at the beginning of December 2019. We realize it is fairly far out of the city proper, is it easy to get taxis to & from the hotel? We know we can have one called by the hotel, but how long does this usually take and what sort of price are we looking at to go to Forbidden City or Summer Palace? Is it easy to get a taxi for the return trip? Our first time in China (but since we got a 4 year visa with multiple entries at 60 day stays, not likely our last :) )
