It is very disappointing that your trip was not what you expected. There are several points to discuss, but overall:
1) This is the first time, in hundreds of reviews, that there have been complaints about the themed music. The guide offered to Bluetooth music from your phone but you declined, The guide asked throughout the day if the volume was okay and you never responded.
2) We find it unbelievable that you thought the stops were too long (and you are exaggerating when you say that we stayed more than 15 minutes). We pride ourselves in giving a complete experience to all our passengers. Unlike other companies that do a quick hop-on/hop-off photo stop, we give the chance to actually experience the grandeur at each of the incredible view stops that we make. One of longer stops, El Capitan, is NOT one hour. It is long enough to set up the telescope so you can see rock climbers (a fun bonus that other tours do not offer). The stop is 25 minutes. You are the first ever to complain about it.
3) It's odd that felt we spent too much time at El Capitan, but you wanted more time for the hike to the Giant Sequoias. You are given 75 minutes to complete the hike, mainly because most people come back from the 2-mile round trip in an hour. The guide said that you returned in 45 minutes.
4) During COVID, our dinner choices are limited. There are no restaurants on the route where indoor dining is available.
5) The posted gratuity sign is there to explain to non-Americans about the custom of tipping in the US. It is suggested and not required, The sign also says that “if you have any problems along the way, please let us know immediately.” And we are curious why you did not speak up.
We are sorry that the experience did not live up to your expectations. And thank you for giving us your feedback. We have noted your comments and will take them into consideration for future tours.
