Hello ,
Greetings from Shopify.
Option 1 - Wordpress (Theme based or custom 2 options)
Option 2 - PHP (Custom design , but takes time as we need to build admin side dynamic option too but better flexibility, easy to manage, For Future updates easily can be made)
1 For both option you need to provide us, Module list, functionality, Do you need inquiry form only or booking and payment option too?
2 What is the deadline? Budget?
3 Do you have any reference website to share for idea?
