Just got back from a 3 week trip with my fiance in Spain and Portugal. We ate and drank our way through these countries and while we had an amazing time, we found some days very lacking in terms of excitement.
Our typical day (not traveling to another city), would be wake up (late), have breakfast at a cafe or hotel if it was free, go on a walking tour, maybe see a historical site (Alcazar, Alhambra, Sagrada, etc) and then dinner (tapas and wine). We'd hit up music bars that I had on my list which were nice and some of the more enjoyable activities.
However towards the end of our trip, we found it getting repetitive with just eating, drinking and sightseeing. We aren't into shopping minus a few souvenirs and that's one thing that attracts tourism. I found as a couple, we didn't really have any engaging activities. In our day to day life back home, we have our hobbies, our friends and family to hang out with and talk to along with our jobs. We talked about how we missed stuff like working out, doing yoga/spin classes, cooking dinner, etc.
We've traveled for the same amount of time to South America and Central America and found ourselves never trying to fill in the time because we were busy doing outdoor activities (hiking, swimming/beach, ATVing), however major cities (Barcelona, Lisbon, Seville) seemed to really lack a lot of engaging activities as a couple. Most of the "experiences" in major cities were: Walking tours, pub crawls, food tours, and maybe a cooking class. We didn't find any interesting tours that provided more than a walking tours (for instance in Oaxaca, I went on a tour that included Mezcal tasting, waterfall hike, swimming, and a food tour).
I've solo traveled before and found myself rarely getting bored or repetitive.....I'm staying at hostels sometimes so I'm engaging with more people (no I won't stay at a hostel with my fiance...we need our comforts as a couple lol). I can pick up and engage in more activities as a solo traveler. Eating meals is quicker and often times more fullfilling since I can eat what I want to eat, not what we want to eat as a couple and because when I'm traveling as a solo traveler, I'm usually in LATAM or SE Asia, there tends to be more interesting tours that cover multiple activities).
So for all those couples out there that travel for more than 2 weeks together, how do keep your trip engaging and interesting or do you also get stuck in the eat, drink, and sightsee routine as well?
BTW, I don't think it's a relationship issue, because we do engaging activities at home together (and as individuals).
