Issue with tour booking flow

Thanks a lot for this tour variation.

1. I need this 3 type of tours in dropdown and when i select one from it, it will show the options for that. Is it possible or not ?
2. If i select 1 adult from any tour, it will automatically add 21 pound extra to the ticket. In admin panel, i have to add some amount.

3. The tour page is very much confusing. Is there any way to make a simple booking block ? where someone select one of the variation and fill number of people and make the checkout.

4. Will it work with WOOBOOSTER (https://booster.io/) in this new release?
