Here are the best hotel loyalty programs to consider for stays in Sweden, with a short summary of why each is useful and who it’s best for. I’ve cited official or recent sources where possible.

1. Scandic Friends (Scandic Hotels)

• Why: Scandic is the largest Nordic hotel operator with a dense network across Sweden (city and regional properties). The program was rebuilt in 2024 with more membership levels and benefits; Scandic also announced a strategic partnership with SAS (EuroBonus) that adds status‑matching and point conversion options in 2025 — useful if you combine flights and hotel travel in the Nordics. (scandichotelsgroup.com)
• Best for: Frequent travelers within Sweden and the Nordics who stay in midscale/upper-midscale city and business hotels.

2. Strawberry / Strawberry Rewards (formerly Nordic Choice)

• Why: Strawberry (the company behind many Clarion, Quality, Comfort and boutique properties) is the major Nordic group that rebranded from Nordic Choice; its loyalty offering (Strawberry/Strawberry Rewards, formerly Nordic Choice Club) is strong across Sweden and often includes breakfast/upgrade perks and local experience offers. It’s particularly strong for urban and lifestyle properties. (nordichotels.com)
• Best for: Travelers who prefer trendy, design-oriented and lifestyle hotels across Swedish cities and events.

3. Radisson Rewards

• Why: Radisson Blu and Radisson properties are common in Sweden (airports and city centers). Radisson Rewards is straightforward to earn/redeem and offers member rates, bonus-night redemptions and upgrades. The Radisson site lists member benefits and how to earn/redeem in Europe. (radissonhotels.com)
• Best for: Business travelers and tourists using airport/city-center hotels (e.g., Stockholm, Gothenburg, Malmö).

4. Accor Live Limitless (ALL)

• Why: Accor brands (ibis, Novotel, Mercure, etc.) operate in Sweden and Accor’s ALL program is global — useful if you mix economy and midscale international stays. ALL often offers frequent promotions and partner benefits across Europe. (Accor brand presence in Sweden makes this program a practical choice for budget-to-midscale stays.) (emea.marriott.com)
• Best for: Travelers seeking reliable budget and midscale options (ibis/Novotel) with frequent promotions.

5. Marriott Bonvoy

• Why: Marriott (including Design Hotels, Autograph Collection and several Marriott brands) has a presence in Stockholm and other Swedish destinations. Bonvoy is valuable if you prefer higher-end and international-brand consistency and want to earn global elite benefits. (emea.marriott.com)
• Best for: Travelers who prefer international full‑service and upscale hotels, or who value global elite status.

6. Best Western Rewards

• Why: Best Western has many independent and branded properties across Sweden and offers easy-to-understand benefits (member discounts, points that don’t expire in some regions, tiered perks). Good coverage for smaller towns. (bestwestern.se)
• Best for: Travelers visiting regional Sweden, smaller cities and towns where small/midscale Best Western properties are common.

How to pick the right program

• Follow your patterns: pick the program that covers the hotels you actually use most in Sweden (Scandic and Strawberry/Strawberry Rewards cover the widest Swedish footprint). (scandichotelsgroup.com)
• If you mix flights + hotels in the Nordics, Scandic’s partnership with SAS (EuroBonus) makes Scandic Friends particularly interesting for 2025 and beyond. (scandichotelsgroup.com)
• For global consistency (business trips outside Sweden), Marriott Bonvoy or Accor ALL may be better because of global brand reach. (emea.marriott.com)

If you’d like, I can:

• Compare two specific programs you’re choosing between (e.g., Scandic vs Strawberry) and show which gives faster elite status or better free-night value for typical Swedish rates.
• Look up which program is best for a particular city or route in Sweden (Stockholm, Gothenburg, Kiruna, etc.).
