We are going to visit Hearst Castle one day in April and want to take 2 tours, Tour 1 and Tour 2. Each is 1 hr and 45 min. How long should I plan to allow between each tour, to allow time to have a little lunch and make the next tour? Would 2 hours between the end of one tour and the beginning of the next be about right? or way tooooo long or short? Thanks so much for any info you can provide.
