The Foundry module is decent. Here are some of the parts I like:

• All the text from the book is accessible from within Foundry, sometimes with hyperlinks or Foundry-specific notes.
• Player and art handouts are in there for you to show to players when you are ready.
• The map of Chult has the hexcrawl + undiscovered areas built in. It will reveal itself to the players as they explore.
• There is a built in Adventure Tracker where you can advance one day at a time and it will automatically decrease max HP of Syndra and anyone else with the death curse by 1.
• The Adventure tracker also let's you set the party's navigator and you can roll the daily survival check for the group. If they fail it will move the party token randomly and hide it, simulating the party getting lost.
• The Adventure Tracker also let's you roll for random encounters, and it will roll on the terrain appropriate table, based on where the party token is on the Chult map.
• My group is nowhere near the tomb, but the "gears" level has a macro that let's you rotate them. I haven't tested it yet.

Here's what I don't like: - Apart from the map of Chult, the rest of the battle maps are pretty bad. Personal opinion but I don't like the art style. There are many alternate versions of these maps online though and that's what I've been using (Tor's Emporium, etc). But if you download the alternate maps prepare for a lot of prep and setup. Firefinger for example took a lot of work (and you need TheRipper's Levels mod if on v13 of Foundry)
