Help with Italian coast tips and recommendations

Hi all, my fiancée and I are getting married in Tuscany at the end of May 2025. We’d like to spend about 5-7 days after the wedding somewhere on the Italian coast for our honeymoon. With all the stress of wedding planning, I really don’t want to do all the planning for this honeymoon too and have frankly been putting it off as much as possible😅 There’s so much info out there that it’s been really tough sifting through it all to figure out what’s really worth it. Budget excluding flights is up to 5k max in addition to racked up Amex and Marriott points.

What we could use some advice on:

1. Location(s) – we’re super flexible on this. Ideally it’s along the coast and has stunning views and enough to do for around 3-5 days. Don’t want to move around too much but open to going to more than 1 city if they’re close!

2. Travel agent – see wedding stress above. I’d love to hire an affordable professional to help us coordinate this! I get a ton of ads for Fora but idk if they’re legit. Totally open to suggestions!

3. Hotel recs – would love something that feels special + a view. Even better if we can use our Amex platinum or Marriott bonvoy points or Amex special offers/statement credits

4. Activity recommendations – we don’t want to overbook ourselves, but would love to hear from others who honeymooned in Italy if any activities really stood out as a highlight ❤️

Thank you so much for your help!
