My husband and I want to visit both Xel-ha and Tulum (maybe Coba too) and have seen that there are excursions that take you from your hotel to Tulum (for a 2 hr stay) then on to Xel-ha for 4.5 hours. This is our first visit to Mexico. We're only interested in "organized" tours as we're not comfortable organizing our own transportation. Should we consider doing both Tulum and Xel-ha together in a one day excursion or will we feel rushed and wish we had allowed more time at each? Just wondering if those who've been there can offer some advice. We want to learn about the local culture and we want to snorkel and see the local eco-systems too!
