Wipree Jess and Wade!
We have stayed at both Travellers and Treehouse so I will give you a little comparison. The property at Treehouse is gorgeous and we found the basic room very comfortable and up to date, Travellers is a bit more modern now, but they are very close in comfort and function. The beach area at Treehouse is much bigger and much deeper, you also don't deal with the backflow from the river so the water does not darken on some days. We were at Travellers last week and this happened two out of the 7 days and just a slight bit on a third day. Travellers has more things going on now as they have some sort of entertainment each night including their beach party on Monday nights w/buffet dinner. Both resorts have great security, Treehouse can get a bit hectic when the cruise ship passengers come in. I didn't really care for that as it seemed the resort became a bit crowded. I also liked that the bar and restaurant prices at Travellers were more reasonable, nothing is overly priced. The breakfast at Travellers is definantly much better, and the view is great as well. One of the things we like about Travellers is that it truly is right on the water. Negril Treehouse has a great location as well, but you are set back a bit. Negril Treehouse has some extra food options with the open grill area and Hollywood doing the chicken each day, so that is a plus.
There isn't too much of a difference as far as location to Three Dives, you will still have to taxi from either. Also, and this is purely personal preference we prefer the location of Travellers as you can walk to local markets, town, etc. It just seems more of the places we frequent are in close proximity. I recommend both as they are both great properties and it truly just comes down to some personal preferences. We prefer to do a split stay and in December we will do 5 nights at Travellers and 3 or 4 at Catcha.
I guess for us we choose Travellers because of the closeness to the water. I love having breakfast right on the water, I love having drinks so close as well. Even if you sit at the bar you still feel close to the sea. Treehouse has a good bar as well, I just prefer the set up of Travellers. Also, you don't deal with as many hustlers on the far end of the beach at Travellers, Treehouse because of being between Margaritaville and Couples is like direcly in the crossfire of all the hustlers. This last trip we would walk each morning from Travellers down to Beaches which is a bit over 2 miles each way and we would not be approached until we got around Margaritaville.
If you have any questions, just ask away!
Both the Wellingtons at Travellers and Gail at Treehouse are top notch owners and I consider the best in Negril, the staffs reflect the owners at both resorts. I am sure we will
