We recently stayed from a Sunday to Thursday at the Adler. My mother-in-law, myself and my 3 sons arrived after visiting Venice and Florence. The Adler was SO relaxing in comparison to the busy and crowded cities. My boys loved the kids' club (except the horseback riding where they had to wait their turn to ride the one horse around a circle). The kids' club staff were excellent and friendly to parents and kids. I loved that you could take them in and out as you pleased since it was all included in the price. The food was plentiful and very good. The hot springs pool was large with different places to sit in the massaging bubbles. The family suite fit our group very well and even had 2 bathrooms. One excursion we wanted to do was fully booked unfortunately. The spa services were excellent! Hoping to return here or to the Adler-Dolomites.

We have just returned from a 7-night stay at Adler thermae hotel with our two very young daughters. We were thrilled with the beautiful food, friendly service and the wonderful spa pool. Our family suite was comfortable, clean and warm. The babysitter we used was outstanding and we all returned feeling healthy, refreshed and well-rested. A very lovely spot. Thank you!

Mostly the good things have been said - it was an excellent stay from the pools to the food , so I thought would add some things not mentioned

Wine Tasting - worth it to see the celler and recommendations from them. Enjoyable evening and meet a couple and family - we all ordered the recommended wine (Cannalli) was great.
Cycle Tours - brilliant - probably the best bikes I have seen in a hotel and a brilliant tour guide - we did both tours
Restaurant - service was excellent and food great, perhaps they need to split the service to allow people without kids to enjoy it without kids - was a few young babies crying at 9:30 pm.
Local village - walk up the hill to Baggio - it is lovely for a sunset drink and 5 mins walk from the hotel.
Gym and running track - great well marked outdoor running track and excellent gym staff and equipment - always space and help

My husband and I took a day spa entrance (entrance fee EUR 50 plus a mandatory treatment chosen freely from the extensive spa menu) and thoroughly enjoyed our time. Luckily it was not high season, so the spa was tranquil. The spa was beautifully designed with a lot of attention to detail throughout: inner courtyard cut right out of the travertine, an olive-wood sauna powered by a watermill, clever use of space to create intimacy, well-finished steam rooms, appropriate lighting, lovely landscaped gardens and a nice variety of jets in the thermal bath outside. Really excellent - pricey but worth it. And did I mention the professional and well trained staff? We will be back next year!
