Looking for an ideal CRM Solution for a small successful travel agency who just focuses on group trips!

Thanks for the help! I currently own a company that plans group trips to Antarctica. I run 3-4 trips a year. I run a Facebook group with over 10,000 members where I get 99% of my leads from. Most of the messages come in via FB messenger or through a Google form I create for each trip that propagates to a google sheet. So far it works pretty good for me because it's very automated. I only ever need to enter minimal data and the sheets take care of the rest. I'm just looking to expand to other locations like Greenland, and the Arctic and would like to build a better system for managing clients. I used hubspot for 8 minutes and it screwed up all my google forms and sheets so I deleted it immediately.
